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 San Juan to Louisville 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 San Juan to Louisville.

What is the typical flight duration from San Juan to Louisville?

The route from San Juan to Louisville spans about 1,810 miles. There is no scheduled nonstop service between these airports, so the flight requires a connection. No flight time can be given for a nonstop leg because none exists.
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 San Juan to Louisville?

There are no non-stop flights from San Juan to Louisville; the quickest routing connects through Charlotte on American Airlines, with a 3h 54m first leg, a 52-minute layover, and a 1h 27m second leg totaling 6h 13m. Southwest also offers one-stop options via Baltimore and Orlando, at 6h 40m and 6h 50m respectively.
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.

What are the ground transportation options in Louisville?

Getting from Louisville Muhammad Ali International Airport to downtown is quick and easy, with taxis and rideshare services like Uber and Lyft being the fastest and most-used options, typically taking 15–20 minutes. The TARC bus system offers an affordable public transit alternative, with route 2 serving the airport and reaching the city center in about 7 miles. Rental cars are available at the airport, and many local hotels provide shuttle services for their guests. Rideshare pickup zones are conveniently located just outside baggage claim on the lower level. Taxis and rideshares are generally the preferred choice for most travelers given the short distance and direct service.

When is the cheapest time to fly from San Juan to Louisville?

Fares from San Juan to Louisville are lowest in late January, around $372. February is the cheapest month overall, averaging $387, followed by September ($388) and October ($391). July is the most expensive month at about $443, and fares peak in late June at about $450. The yearly average is $404. 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 San Juan to Louisville?

Book about 4 weeks before departure for the best fares from San Juan to Louisville, around $384. Booking in the final days before the flight costs about $467, $83 more. Booking six months ahead runs about $651. 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 San Juan to Louisville?

Yes, overnight red-eye connections are available from San Juan to Louisville, via Orlando. The overnight leg departs San Juan at 10:50 PM on Southwest, arriving in Orlando at 1:55 AM (in the early hours), before connecting onward to Louisville after a long layover.
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 San Juan to Louisville?

There is no nonstop service from San Juan to Louisville; the common one-stop routings are on American Airlines via Charlotte, Miami, or Philadelphia, Southwest Airlines via Baltimore or Orlando, and United Airlines via Chicago O'Hare or Newark. American Airlines offers the most frequent connectivity, with Charlotte as the quickest routing at about 6 hours 13 minutes total travel time. Southwest connects through Baltimore and Orlando, while United routes through Chicago and Newark, though United's itineraries tend to run longer. No typical per-carrier fares are provided 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.

Which airport should I use in Louisville?

Louisville has one commercial airport, Louisville Muhammad Ali International Airport (SDF), about 6 miles south of downtown and convenient for Churchill Downs and the Kentucky Exposition Center.

How do I get to Luis Munoz Marin Intl Airport from the city center?

From downtown San Juan, you can reach Luis Muñoz Marín International Airport by public bus (routes T5 and D53 stop on the upper-level roadway outside Terminals A and B), by taxi (both metered street taxis and fixed-rate tourist taxis, with dedicated pickup areas at Terminal A arrivals and Terminal B arrivals), or by ride-share through Uber or Lyft, which have designated pickup zones at Terminal A and at columns 16–19 of Terminals B and C. Taxis and ride-shares are the most popular and fastest options because they offer direct door-to-door service in about 15–25 minutes, while the bus is the cheapest but slower and less frequent. Driving yourself is also possible, with over 4,500 short- and long-term parking spaces at the airport, though parking in San Juan can be expensive and traffic is often heavy. Hotel shuttles from many area properties provide another convenient middle-ground option.
References

Are there hotels or sleeping facilities at Louisville airport?

Louisville Muhammad Ali International Airport has several hotels nearby, including the Residence Inn by Marriott Louisville Airport, Springhill Suites Louisville Airport, and Hampton Inn Louisville-Airport, all within about half a mile of the terminal. Some of these nearby hotels offer airport shuttle service, and courtesy phones in the Ground Transportation area can be used to arrange pick-up. The airport itself has no dedicated sleeping areas or cots, so for uninterrupted sleep travelers should book one of the nearby hotels.

What aircraft are typically used on flights from San Juan to Louisville?

American Airlines operates the most service, using Airbus A321s on the long leg to Charlotte, Miami, or Philadelphia, with Airbus A319s, A320s, or Embraer E175s on the short leg. Southwest connects through Orlando or Baltimore on Boeing 737s, and United offers one daily connection via Chicago or Newark using Airbus A321neos or Boeing 767-400s.
Methodology
Aircraft types 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). For U.S. routes the type is grounded in the tail number that actually operated the flight; elsewhere it comes from 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, 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.
