Everything about this flight was good...EXCEPT the wifi.

Wifi is so madly expensive I will not fly United for business EVER (or a lot of pleasure--since often I have to catch up on work when in flight). Very disappointing. $40 for wifi is obscene...and the service was spotty. You know: my last few JetBlue flights had COMPLIMENTARY wifi--and it was good. I will fly JetBlue in the future whenever I need to be online. Really annoying, United.

For an extremely late gate arrival, United personnel were very accommodating.

One flight attendant was more than curt and impatient when taking food orders. Cabin announcement told passengers to check menu in setback pocket. There was no menu. Attendant didn't offer one until another passenger who overheard conversation requested menu. As a frequent United traveler BOS > SFO, normally a 5-6 hour flight, attendants always seem to be rushing, brusque.

I always love to fly Sun Country. In flight everything has always been awesome.

I went to the counter in Denver to ask the gate agent where my seat was (middle or aisle) and if I could get it moved. The agent said he would help me once he was done setting up. I sat there for 15-20 minutes while he moved the ropes around (for the line), set up his mouse, found a mouse pad and set that up, found signs to put up at the desk and made sure they were in the right spot. He was on the computer for a good 5 minutes writing notes on a paper. I waited patiently, but was getting really annoyed that he couldn't look up my seat quick and then go back to setting his desk up. Finally, he took my ticket, did not apologize for my wait or thanked me for being patient, and just said he had no seats. I waited 20-minutes, which then I didn't have time to eat before we boarded the plane. I was extremely disappointed in him telling me he'd help, did not communicate that I needed to wait for him for that long and then wasn't nice enough to thank me for waiting. Incredibly disappointed in this service.

Boarding is easy. Friendly service.

My bags never made it on the plane, and it wasn't specifically located because you don't scan bags until they arrive at their destination. It's more than a little inconvenient because I couldn't change clothes, but I also didn't have to drag my bag to the hotel.

We ran into a combination of traffic, parking, and other issues that drove us to arrive at our check-in at 7pm for a 7:40pm flight. We were not able to check-in given the 45 min rule. NO WHERE in our email did it say there was this rule nor were we prompted or told to check-in prior to our flight online. There's no suncountry app for check-in that we could find (only a visa one). We booked through priceline.The flight hadn't even started boarding and we were not allowed to check-in. We were re-booked on a flight that left two hours later, but that flight was delayed 3 hours. The whole thing essentially took one full night of paid hotel and fun in Vegas away costing us over $200 just in hotel plus we spent an extra 5 hours in an airport that didn't have a bar open past 9pm.

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

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 the prices, so it’s not possible for us to guarantee what other companies are selling.

We compile tonnes 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 can't guarantee prices we find.

Why aren’t prices accurate 100% of the time?
Prices on airline seats, hotel rooms and car rentals 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.

If you have more questions or if you have a bad price to report to us,
please send us an 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.
