Methodology: learn how we calculate these charts

The charts “When is the cheapest time to fly?”, “How far in advance should I book?”, “What's the cheapest day of the week to fly?” and “What do round-trip flights from Seattle to New Orleans cost?” are built from the prices Priceline customers actually paid for flights on this route over the past 12 months or more.

Where a route has too few bookings to fill every point in a chart, we borrow the shape of the curve from a group of routes with similar price behavior and fit it to the fares booked on this route.

Because past fares don’t reflect today’s market, we then adjust the historical prices for current conditions such as inflation and fuel costs, using the round-trip fares found in recent searches on this route.

The chart “When is the best time of day to fly?” is calculated directly from the fares found in recent searches, not from historical bookings.

Frequently Asked Questions

Everything you need to know about flying from Seattle to New Orleans.

What is the typical flight duration from Seattle to New Orleans?

The flight from Seattle to New Orleans is about 2,080 miles. Nonstop service takes roughly 4 hours 35 minutes outbound, while the return leg runs about 5 hours 6 minutes — the westbound return is longer by about half an hour due to prevailing winds.
Methodology
Flight times and distances come from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). The typical flight time is the median scheduled block time across all carriers on the route, computed the same way in both directions so the difference reflects prevailing winds rather than any change in method. Distance is the great-circle distance between the two airports, so the actual flown track is typically 2-5% longer.

Are there any direct flights from Seattle to New Orleans?

Alaska Airlines flies nonstop between Seattle and New Orleans, with two daily departures — one at 9:37 AM and one at 11:13 PM — for a total of 14 nonstop flights each week, every day of the week. Alaska is currently the only airline scheduled nonstop on this route, operating Boeing 737 family aircraft with a typical flight time of about 4 hours 39 minutes.
Methodology
Airlines and weekly frequencies are compiled from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). We count each operating carrier's scheduled weekly departures and the days it flies; where there is no nonstop service, connecting carriers are identified by linking scheduled nonstop segments through common hub airports. Where a median fare is shown for a carrier, it reflects the real fares Priceline users found on this route in the last 72 hours. Carrier service, flight times and distances for this route come from our flight-schedule database, which draws on published airline timetables, U.S. government schedule data, and observed operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). We report the days of the week and the departure times each carrier operates. The typical flight time is the median scheduled block time, given both per carrier and across all carriers on the route; where a schedule does not publish an elapsed time, it is derived from the scheduled departure and arrival times converted to UTC. Outbound and return times are computed by the same method, so the difference between them is directly comparable and reflects prevailing winds rather than any change in derivation. Distance is the great-circle distance between the two specific airports named, so an actual flown track is typically 2-5% longer. Where an aircraft type is shown, it also comes from this database: for U.S. routes it is grounded in the tail number that actually operated the flight, and elsewhere in the airline's filed equipment code. Where the source does not commit to a specific variant we name the aircraft family (for example "Airbus A320 family") rather than guess a member, and where no reliable type is on file the aircraft is simply omitted rather than estimated. Flights known only from the OPDI feed carry no aircraft type, because their flight numbers are synthetic and joining by flight number would attribute another flight's aircraft. Where shown, on-time departure and arrival rates and cancellation rates come from the U.S. Bureau of Transportation Statistics (BTS) Airline On-Time Performance dataset, which covers U.S. domestic routes only; where a typical fare is shown, it comes from the U.S. DOT Airline Origin and Destination Survey (DB1B), a quarterly 10% sample of tickets sold.

What are the ground transportation options in New Orleans?

From Louis Armstrong New Orleans International Airport (MSY), about 11 miles west of downtown, the fastest option is typically a taxi or rideshare, both of which pick up on Level 1 outside baggage claim and reach the Central Business District or French Quarter in roughly 20 to 30 minutes. Taxis offer a flat rate of $28 for the first two passengers to downtown, while rideshare services like Uber and Lyft operate around the clock from the designated middle curb. Public transit is the most affordable choice, with Jefferson Transit (JET) and RTA buses running from Door 2 to downtown, though the trip takes longer and involves local stops. Rental cars are available at a consolidated off-airport facility on Rental Boulevard, and many hotels also run courtesy shuttles from the Ground Transportation Center. Rideshare and taxi are the most-used options for visitors heading straight to the French Quarter.

When is the cheapest time to fly from Seattle to New Orleans?

Fares from Seattle to New Orleans are lowest in late January, around $338. January is the cheapest month overall, averaging $344, followed by August ($351) and September ($352). December is the most expensive month at about $414, and fares peak in late December at about $450. The yearly average is $374. Fares are adjusted to current market conditions.
Methodology
Seasonal fares come from Priceline's own air booking-summary archive, analysed in-house and refreshed monthly. For each day of the year we take a representative round-trip fare, a blend of the 25th-percentile and average ticket price over the route's bookings, and smooth the series into a seasonal curve; the half-month low and high and the monthly figures quoted here are averages of that curve. Thin and international routes borrow their seasonal shape from the nearest busy routes, with the price level anchored to the route's own bookings.

How far in advance should I book tickets from Seattle to New Orleans?

Book about 5 weeks before departure for the best fares from Seattle to New Orleans, around $265. Booking in the final days before the flight costs about $317, $52 more. Booking six months ahead runs about $373. Fares are adjusted to current market conditions.
Methodology
Booking-window guidance comes from the same monthly in-house analysis of Priceline's own air booking-summary archive. We aggregate the route's bookings by how many days before departure they were made, from about 180 days out to the day of travel, smooth the curve, and highlight the stretch of lead times with the lowest average fare. Thin and international routes borrow the curve shape from the nearest busy routes, anchored to the route's own price level. It reflects current fares and is refreshed monthly.

Are overnight (red‑eye) flights available from Seattle to New Orleans?

Yes, Alaska Airlines operates a nonstop red-eye from Seattle to New Orleans, departing around 11:13 PM daily and arriving at 5:49 AM the next morning.
Methodology
Red-eye flights are identified from scheduled local departure and arrival times and block times in our flight-schedule database — built from published airline timetables and official schedule data, including U.S. Department of Transportation records for domestic routes. A flight counts as a red-eye when it departs in the afternoon or evening (3 p.m. or later local time) or in the early hours before 4 a.m., and is in the air at some point between midnight and 4 a.m. local time at both its departure airport and its arrival airport. An evening flight that lands before midnight at its destination is never counted, nor is a morning departure or a daytime long-haul that reaches the next calendar date only because of time zones. Each red-eye is labelled with its timing (for example, overnight and landing the next morning, or late-night and landing after midnight). For connecting itineraries the same rule is applied to the longer leg, from one representative day's flight search.

Which airlines usually operate this route from Seattle to New Orleans?

Alaska Airlines operates the only non-stop service from Seattle to New Orleans, with 14 weekly flights departing daily at roughly 9:37 AM and 11:13 PM. Alaska is a oneworld alliance member. No median fare is listed for this route.
Methodology
Airlines and weekly frequencies come from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI). We count each operating carrier's scheduled weekly departures and the days it flies; where there is no nonstop service, connecting carriers are identified by linking scheduled nonstop segments through common hub airports. Where a typical fare is shown for a carrier, it is the median of the real fares Priceline users found on this route in the last 72 hours.

How reliable are on‑time arrivals on this route from Seattle to New Orleans?

Alaska Airlines is the sole carrier on the Seattle–New Orleans route, with an on-time arrival rate of 74.9% and a cancellation rate of just 0.5%. Its flights land within 15 minutes of schedule about three-quarters of the time, making it the most reliable option on this route.
Methodology
On-time arrival and cancellation rates come from the U.S. Bureau of Transportation Statistics (BTS) Airline On-Time Performance dataset, which covers U.S. domestic routes only; a flight counts as on time when it arrives within 15 minutes of schedule. Carriers are ranked by arrival on-time rate on this route, and the carrier list itself comes from our flight-schedule database, which combines published airline timetables, U.S. government schedule data from the Bureau of Transportation Statistics (BTS), and observed flight operations from the EUROCONTROL/OpenSky Open Performance Data Initiative (OPDI).

Which airport should I use in New Orleans?

New Orleans has one commercial airport, Louis Armstrong New Orleans International Airport (MSY). It is about 15 miles west of downtown and the French Quarter, with taxi and rideshare service taking around 25 to 35 minutes.

How do I get to Seattle-Tacoma Intl Airport from the city center?

From downtown Seattle, the Link light rail is the most popular and economical way to reach Seattle-Tacoma Intl Airport, taking about 38 minutes from the city center with trains every 8-10 minutes, and an overnight Night Bus fills the gap after the last train. Taxis to the airport run on a meter with a $20 minimum fare plus a $1 on-demand surcharge, and ride-share services like Uber and Lyft pick up on level 3 of the parking garage for a 20-30 minute trip. Shared and private shuttle services serve the Seattle-Tacoma-Bellevue-Everett corridor for hotel and residence pickups, while driving takes about 30 minutes via I-5, though downtown parking can be expensive. The light rail is generally fastest during peak traffic and cheapest overall, while taxis and ride-shares offer the most direct door-to-door convenience.

Where the source does not commit to a specific variant we name the aircraft family (for example Airbus A320 family) rather than guess, and where no reliable type is on file the aircraft is omitted rather than estimated. Types describe typical scheduled equipment and can vary with seasonal or day-of-week assignments and last-minute swaps.
