Top tips for finding a cheap flight from DEN 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.

Horrible experience. They "GAME" with seats they decided to play where you can`t select or get seat during check-in without paying and then forcing you to stay long line at the Customer Service at the gate to get a boarding ticket with seat assigned is pathetic. Will never fly with United again!

Horrible experience. They "GAME" with seats they decided to play where you can`t select or get seat during check-in without paying and then forcing you to stay long line at the Customer Service at the gate to get a boarding ticket with seat assigned is pathetic. Will never fly with United again!

So terrible. They would not rebook me for a flight until 2 days. I had to spend so much money to get my own flight. They were rude and not helpful.

Overall a good experience, the flight was on time, the crew very attentive and friendly. However the seats are too cramped, there is no space, and as soon as the person in front reclines the seat, it's literally in your face.

Bag lost. Lost bag recovery process is an unsatisfying customer experience. Because 1) bag is still lost but also 2) the process is outdated and form-heavy and 3) in our case also involved a long line.

We were very impressed with Swiss Air. The service was exceptional. Unfortunately, we had a baby behind us that screamed for hours. , It was a nightmare, though I completely understand that it was not Swiss Airs fault.

We had to move to terminal 5 for the next part of our trip. Very un-organized and difficult.

Missed connecting train since flight was late into Zurich and I had to stay at airport hotel because of it as well as I had to repurchase train ticket

Cons: "Flight was completely full and certain passengers were belligerent about wearing face masks. The cabin crew did not enforce mask wearing, stating “we are not the police”"
Pros: "Nothing. There was no flight. The flight was cancelled and you did not notify us. We found it out ourselves by accident. We tried to contact you guys but we could not call or anything other. You guys suck"
Cons: "Notify your customers when the flight is cancelled. Thats the least you can do. Very unprofessional"
Cons: "I fell sick and my doctor advised against flying. Tried calling Swiss Air and JustFly.com: 6 calls back and forth and 7 hours on hold, no help. Finally got advised on driving to the airport to make the flight change at the Swiss Air counter at O’Hare. The representative told me to bring a note from doctor to switch flights. I did the next day. The same representative looked me in the eye after advising the day before and said there’s nothing she could do. Why make an elderly sick person drive to the airport again if you know already you cannot help??Absolutely terrible experience, no help from the airline or travel agency. Total loss of the full price of the ticket."

German crew were very kind. Food was okay but can be better, especially bread was not good, Garbage collection was very poor.

Awful Terrible staff poor communication Flight delayed for an hour with no apology or explanation and no help re missing connecting flight. Resulted in a 7 hour layover at Munich waiting for another connecting flight. Only 15 euros refreshment voucher given. Will not fly Lufthansa again

Both flights were late for what appeared to be the airline’s not having the planes ready. Arrived over 6 hours late.

It was a busy flight and all the crew were very helpful and gracious

Seats were not the most comfortable and food options weren’t great but overall but everything else was excellent

Check-in very easy and smooth. Plane and crew were nice. Seat open next to me created more space. Food was fair but plentiful. Lots of movies and I was able to sleep some on the way to Munich. Very tight connection, about an hour. Fast through passport control and a bit of a walk to last G terminal gate but I made my connection to Palma. Unfortunately, my luggage did not make it. It is now almost 24 hours since I anded and still NO luggage. I know it landed last night on another flight. Local delivery should be today to my hotel in Palma but nothing yet. I asked about the tight connection when I checked in and was assured they would get my luggage to the connecting flight. Very disappointing it missed my flight but more disappointing that it has taken so long to arrive. Failure on the airlines and service to get my luggage to date.

I wish the flight attendant was a little bit kinder

The food wasn’t great and it would be nice if the airlines showed documentaries about the countries we are flying into.

Disappointed everytime. The app doesn't load the boarding passes. They have lots of agent that seem to be busy doing nothing with a long line waiting to get paper boarding passes. Food choices are poor. Entertainment is less than entertaining.

Horrible experience. Nothing to give to kids to keep them entertained.

The seats were tiny, being of a fairly petite build, I don’t usually expect to feel crammed and cramped in a seat, but I definitely was on this flight. I couldn’t even bend over to get anything out from under the seat in front and getting up to go to the bathroom at night with the seat backs reclined was nearly impossible. I had to do gymnastics to get over and out. For an airline that does long flights overnight, it’s kind of ridiculous.

Not connecting flights. Missed my flight from Dublin to Liverpool because I arrived at Dublin one hour too late. For this mistake, they offered me a flight from Dublin to Manchester. Thats great and all, but I waste time and money to commute to Liverpool. Be sure to check the time of your connecting flights, because they sure don’t when they sell it to you

Excellent! Great flight attendants, good food (in business class, at least), very comfortable. Touchscreen and remote wasn’t great.

In economy and food was ok, but with limited leg space (and I was in a 2 seat configuration) it was difficult to eat with a tiny seat tray. I spilt wine on my trousers. First time on British Air (I usually fly Turkish Air) and in a 777. Heathrow was pleasant but changing terminals awkward.

Starting with the flight Cairo to London the plain was so poor no entertainment at all uncomfortable seats although it’s 5 hours long,then an American airline plain took me from London to Miami it was a bad experience the crew most of flight time not available and they asked us to help our selves for any snacks if we need. From Miami to London actually was perfect flight with a huge plain and perfect crew but from London to Cairo was horrible plain with stiff fixed seats not movable no entertainment or wi fi very poor Menu which is unacceptable for a business class

I've done hundreds of flights in my life, and this flight was one of the best I've ever taken, From beginning to end, everything went smoothly, professionally, and with a smile and friendly attitude from all employees I interacted with. The food was delicious (and free), as were the drinks. There was just a genial and effective way in the way that British Airways organized the flight -that reminded of days in the 70's, 80's, and 90's, when flying was a fun, and exciting adventure. I enjoyed and had confidence in the abilities of the flight crew, I'll be flying British Airways several more times this summer. Thank you so much for the great experience! Cheryl Olso

My baggage did not arrived with me. Took 3 days to get it after so may calls and follow up

Terrible! I missed my flight to my final destination and British airlines and American Airlines keep pointing fingers on each other’s. Nobody wants to take responsibility

Terrible. Flight was 3 hours delayed and I missed my other flight to my final destination

Overall, terrific service, accommodations, and experience. Only reason comfort was rated lower was because it was difficult to keep a comfortable sleeping position for the overnight flight, but I also had an economy seat.
