This flight was inexpensive and the layover was very easy. Didn't have to pay to carry on luggage like other cheap options.

No entertainment except movies to rent through flight attendant. Seats were uncomfortable. Airline is in the worst terminals with terrible food options.

I liked the local Minnesota drinks on the menu. Having MN beer was a fantastic touch (Surly Furious is the best!). Sadly, on my departing flight they were all out though.

That you have to pay for drinks. And no peanuts or small snacks was a bummer - that's just cheap (you have to pay for those too)

JetBlue is always an excellent airline to fly. Always know what youre going to get.

The AC was broken or something of the sort, so it was very hot. Made the 6 hour trip extremely uncomfortable.

The flight was delayed just as we were about to board at 5:30. There was a mechanical problem and we were changed to another plane and another gate, which was supposed to take off at 6:30. It was boarded and ready to go around 7:00. Then....we taxied down the runway only to stop because of a situation on THIS plane (a light that did not go off). It was fixed pretty quickly and meanwhile a rep. from Delta boarded the plane, apologizing for our inconvenience and handed out Jolly Ranchers. REALLY? After that, she and the flight attendants did give us a free drink/headset coupon. That would have been nice but it expires Dec. 2017 and the flight attendant stopped serving drinks about half way down the aisle because the flight was so short. The coupon will be of no use to me. I finally got to Raleigh about 9:30...I booked the flight so I wouldn't have to drive at night.. Sigh....Delta used to be my favorite airline.

Although I understand the needed delay, it would have been nice to have been served ice water in the hot cabin, instead of a small cup of tepid water.

I liked that no one was a jerk to us. We had a miserable experience with United on our other leg. I liked that we were allowed to bring on a carry-on and a personal item (always have been allowed to do this and was charged by united to be forced to check my bag which was mind-blowing to me). I asked one of the flight attendants for some water right when we boarded and she was so sweet she couldn't get us a bottle but she brought us a glass and made sure we were ok.

I just wish airlines in general would still give you a reasonable amount of space to sit in. Sun country is no worse than any other airline but I'll be damned if it isn't impossible to take a nap, and my girlfriend can't event sit with her legs straight in front of her. I'd call it inhumane if we weren't voluntarily choosing air-travel. I also really miss free food on airplanes. And what's with only accepting two kinds of credit cards?

Nothing it was a horrible experience, Sun Country would not take any of the passengers calls and we were not told why the flight was our five hours late. The flight crew at JFK was pleasant but they seem to be very nervous and withholding information about why the flight was late and they never actually explained to the passengers why the flight was late.

They did not offer us any explanation nor did they give us any credits there was a very minor apology from the pilot somewhat blaming the crew at JFK which is not fair. I've never experienced service like this from Suncountry airline before and I will definitely think twice before booking a flight with them again .

Prices are per person, are for e–tickets and include all taxes & fees in GBP.

We attempt to get accurate prices, however, prices are not guaranteed.

Here's why:

We’re not the seller
At KAYAK we don’t set prices, so it’s not possible for us to guarantee what other companies are selling.

We aggregate tons of data for you
Our service lets you quickly and easily compare results from hundreds of travel sites at once. In this sense, KAYAK is a search engine and we don't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car hires can change frequently. Several people may also be trying to buy the same travel option simultaneously. As a result, you may find on occasion that certain prices are no longer available.

More questions or if you have a bad price to report to us
Please send us an email and someone from our team will get back to you promptly.

The fares displayed include all taxes and fees for economy class travel and were found by the provider in the last 72 hours. Seats are limited and may not be available on all flights and days. Fares are subject to change and may not be available on all flights or dates of travel. Some carriers charge additional fees for extra checked bags. Please check the carriers' sites.
