KAYAK’s top tips for finding a cheap flight from Denver to Santorini (Thira)

  • The Denver International Airport (DEN) is a hub for United, Frontier, Southwest, and others. Santorin Airport (JTR) serves the island of Santorini (Thira) in Greece and has scheduled flights for Ryanair, Aegean Airlines, and Olympic Air. Some of the cheapest tickets from DEN to JTR involve frontier, Ryanair, and Aegean Airlines.
  • If you have the time, a cheap DEN-to-JTR flight with multiple stops and a self-transfer can be a great bargain. Just make sure that the connection where you have to self-transfer allows you ample time to pass through customs, collect any checked baggage, possibly get to another terminal for the next leg of your flight, and go through security again.
  • On flights from Denver to Santorini (Thira) aboard multiple airlines, some connection cities that come up frequently include Orlando (MCO) Dallas (DFW), Calgary (YYC), Dublin (DUB), Reykjavik (KEF) and London (LGW). On flights with one stop, the connection city is almost always London (LHR).
  • Because Greece is a country that is a party to the Schengen Agreement, Americans do not need a visa as long as they are traveling for purposes of tourism or business and intend to leave Greece within 90 days. If you are traveling to Santorini for other reasons or want to stay longer, you will have to apply for a visa.
  • If you are looking for a cheap ticket but one that also offers a comfortable economy seat, consider a flight that involves Icelandair, especially on the flight leg over the Atlantic. Economy seats aboard Icelandair have 32 inches of seat pitch, seat-back entertainment, and a USB port at your seat.

Very, very tight legroom. They must’ve jammed in an additional few rows of seat seating. Denver to Munich was the least legroom I’ve ever had on any flight, let alone a multi hour international journey. I will not take that flight again.

Very, very tight legroom. They must’ve jammed in an additional few rows of seat seating. Denver to Munich was the least legroom I’ve ever had on any flight, let alone a multi hour international journey. I will not take that flight again.

Very good, i got two seats for myself, and was comfortable with the blanket i got

Food is too little (in volume) and too spicy.. There are no snacks in the back of the plane in between meals.

We had a 1 1/2 hour delay before we left Denver. When we arrive to Frankfort, they didn’t announce that people with connecting flights to exit the plane first. My next flight was already boarding when we we taxiing in to the gate. I waited another 10 minutes to get off the plane. I had to run to catch my next flight. I mean run! I made it with one minute to spare, but my luggage did not. My luggage came two hours later on a different flight.

Both flights were delayed and we missed our connection. Our second flight was delayed 3 times. I have always had great service and never any problems with my flights on Lufthansa. My last two flights were, unfortunately, awful. I fly quite often to Germany and have had better luck with United than Lufthansa.

Excellent staff and flight experience. Would rather that I had upgraded to Premium Economy for extra space, but I will know to do it next time.

It was my first experience in business class. It was everything I expected and more. Service was impeccable, food was delicious and I felt rested once I arrived to London

Sorry, I’m not a fan of United. The seats are just too cramped and uncomfortable if you are traveling very far.

Zero legroom or space in economy. Flight was delayed into Munich causing a missed connecting flight and other missed bookings. :(

Would not accommodate my request to bring my my jacket I left on the plane.
