KAYAK’s top tips for finding a cheap flight from Denver to Thera

  • 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.

The flight delay made the connection a bit tight but that's outside the flight crew's control.

The flight delay made the connection a bit tight but that's outside the flight crew's control.

We just made it to our connecting flight. A long, long speed walk!

We didn't get the coffee with breakfast in the morning.. 30 mins lazer I asked flight attendant why don't we get coffee now at least.. after the breakfast..she said that captain announced possible turbulences fee minutes ago, which didn't ecplain why we didn't get it with the breakfast..breakfast was very poor btw..just little pastry which you can eat in 4 little bites. Turbulences fortunately didn't even happen.. but we didn't get that more than necessary coffee in the morning after the night flight with very poor sleep.. They just served breakfast 1 hour afzer we took off..at like 11 PM.. that doesn't make sense at all.. Also, flight attendants weren't very nice..they looked like they're not happy with their job.. :/

Lufthansa still has a good level of quality compared to US airlines, especially with respect to (1) food quality - actually tasty, (2) good French red wine - free, (3) good movie selection. Also my ticket price includes 1 free check-in luggage, while some other budget airlines sneak in an extra $150 for a checkin.

I think they overbooked Frankfurt to New York and bumped me off. This changed my return travel I arrived home about 4 hours late. Almost 24 total travel time Totally unacceptable Would not travel with United

We were moved twice on flights to the point we weren’t even on Lufthansa anymore. We had to fly united. Lost paid extra leg room twice. To top it all off we’re forced to pay $375 and $275, respectively for you luggage that was considered sports luggage. We were told it would be Lufthansa fares l, from the united desk, AND WE DIDN'T EVEN HAVE A LUFTHANSA FLIGHT! I’ll be calling once my trip is over on October 7th to all airlines and Kayak. This was ridiculous!

Everything went smoothly and the staff was very kind. I’m glad I purchased the extra leg room for my long flight; it was totally worth it. We were served 2 meals for a 9 hour flight which I was not expecting and they were very tasty. I appreciated them being vegetarian. Customs line in Munich was long; I had a choice to have a 1 hr 40 min layover or 2 hr 40 min layover; I took the longer layover which I was thankful for because my flight was delayed 30 minutes and there’s a good chance I would have missed my connecting flight. This was my very first international flight and I would fly Discover again without hesitation. Thank you for taking good care of me!

I liked everything BUT the temperature. It was freezing and now I am sick.

I liked Quiet people around me. Crew could have helped people with overhead luggage so they aren't moving other peoples bags around and causing problems for people that had there bags there first

The flight and crew were good. The customer experience on the ground could have been better. We had to reschedule our flight because of a delay on the previous flight. The attendants working the desk in Washington DC were not helpful. They told us to scan a QR code and that would get us rebooked. Why couldn't two people standing at their computers do this? We had to chat with someone to get everything figured out. It was extremely confusing.
