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.

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

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

The seat I was stuck in was so unimaginably uncomfortable. I have never had that tight of a seat in my 20 years of flying. Even budget airlines give you more space.

We were upgraded to economy plus and everything was awesome!

I liked the crews attentiveness, all food and drink items were tasty, and came out in a timely manner. The entertainment systems were not as responsive and my seat had issues with the auxiliary for the headphones. Seats were OK, and the headrest for my seat could go back only so far. Bathrooms were tight fit.

Our flight was delayed for over an hour due to weather, and it had already been a long travel day. However, the crew was calm and compassionate, listening to every complaint with genuine concern. They got us home safely without incident, in spite of all of the obstacles. I’m grateful.

Hate their old flights, boatding, food and services. Very poor quality

Insulting. Lufthansa flight from Munich to EWR had us getting our luggage when we were told in Florence that it would follow us to Indianapolis. It did not. Then very slow security in EWR caused me and three other passengers from Lufthansa flight from Munich to miss the boarding closure. Behind me were two elderly grandparents and their ten year old grandson. We were all refused entry on a plane to Indy that was still at the gate. The doors had not even closed inside the terminal yet. No apologies or compensation offered. Not even a meal voucher let alone a free hotel stay for our inconvenience. I m not sure what the other three passengers behind me did ( they were elderly with a grandson, recall), but I stated 12 hours overnight in a chilly EWR airport until next flight to Indy at 850 next morning.

The food could be better, more snacks. And have some plugs to chargue the phone.

The pasta in the evening meal was tasteless. Otherwise, the flight was okay.

Everything was really great just The aircraft was too old and sounded it will break during takeoff
