Flight Deals from Denver to Zagreb from $582

The flight from Denver to Zagreb covers about 5,480 miles. There is no scheduled nonstop service on this route, so the journey requires a connection.

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.

There are no non-stop flights from Denver to Zagreb. The shortest connecting routing is on Lufthansa via Munich, with a total trip time of 12 hours 30 minutes (a 9-hour-35-minute first leg, a 1-hour-50-minute layover, and a 1-hour-5-minute final leg). United also offers a one-stop option via Frankfurt at 13 hours 55 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.

Getting from Franjo Tuđman Airport to central Zagreb is straightforward, with the most-used option being the Croatia Airlines airport shuttle bus, which runs directly to the main bus station for about €8 and takes roughly 35–40 minutes.

There are no nonstop red-eyes from Denver to Zagreb, so overnight service is only available via connections. Red-eye long legs depart Denver in the late afternoon and evening — Lufthansa at 16:05 to Munich (arriving 09:40), United at 15:55 to Frankfurt (arriving 09:20), Lufthansa at 17:40 to Frankfurt (arriving 11:15), and United at 20:25 to London Heathrow (arriving 12:25) — each landing the next morning before connecting onward to Zagreb. These overnight legs connect through Munich, Frankfurt, or London Heathrow on Lufthansa, United, and Croatia Airlines.

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.

There is no nonstop service from Denver to Zagreb; travelers connect through European hubs. Lufthansa via Munich and United Airlines via Frankfurt are the most common routings, with Lufthansa offering the quickest trip at 12h 30m. Turkish Airlines also connects via Istanbul, and some United itineraries route through London. All of these carriers are Star Alliance members, with Croatia Airlines operating the final leg on some Lufthansa and United connections.

Zagreb has one main airport, Franjo Tuđman Airport, located about 10 km southeast of the city centre. It serves as the primary gateway for all scheduled flights to Zagreb, with direct connections to major European hubs.

From downtown Denver, the RTD A Line train is the most popular and cost-efficient option, running every 15 minutes around the clock from Union Station to the airport in about 37 minutes for roughly $10. Ride-share services like Uber and Lyft, along with taxis, provide door-to-door convenience in about 25–35 minutes at a higher cost, with designated pickup areas on Level 5 of the terminal. Shared-ride shuttles and hotel shuttles offer a middle-ground option for groups or those staying at nearby hotels, while driving yourself means using the airport's garage or economy lots, which are pricier for extended stays. The train is generally the fastest and most reliable choice during peak traffic, though ride-share wins for direct convenience when time is tight.

Lufthansa operates the most connecting flights, using an Airbus A350-900 on the long leg over Frankfurt or Munich with an Airbus A320, A220-300, or A321 on the short leg.

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.

There is no nonstop service between Denver and Zagreb; the route is flown via one-stop connections, and every carrier operating it — Lufthansa, United Airlines, Turkish Airlines, and Croatia Airlines — belongs to the Star Alliance. So Star Alliance is effectively the only alliance serving Denver to Zagreb, typically via hubs like Munich, Frankfurt, or Istanbul. No major unaffiliated carrier such as JetBlue or Emirates operates this route.
