Okay 4.0

Cons: A very rude boarding agent insulted a young man from another country who was boarding in front of me. He misunderstood that they wanted him to check his luggage instead of carry it on. The agent yelled at him and shamed him in front of other passengers. United strikes again!! Seriously folks, you suck!

Good 6.6

Pros: The middle seat was empty, the boarding process was fast.

Cons: I always feel a bit crowded in United flights, the seats are very close. Tried to used the free inflight entertainment and it didn’t work in my computer, which was a bummer. The arm rest was sticky.

Mediocre 2.0

Cons: We had to run to get to our plane because of the ridiculous time-window you guys allowed (15 minutes if everything went according to plan--which it didn't).

Pros: Left on time, smooth ride, arrived early

Cons: Was in first class front row. I was offered only one drink the entire 6.5 hour flight. The flight attendant in first class never came around and asked if i would like anything else. The potatoes served with the meal were not cooked completely and they let the entire coach section use the forward bathroom so it was like sitting at the very back. Had to wait several times for several others before i could use the first class lavatory. They didn't turn off the cabin lights until very late in the flight so we could sleep. The flight attendant(s) in first class were not friendly. Wifi was horrible and almost not useable. Definitely not worth the $29 I had to pay. I fly this trip regularly and are almost always delighted but this trip was disappointing to say the least.

Pros: There was a huge line for security but a sign telling us to expect a 15/20 minute wait made it more acceptable. The boarding to the Alaska flight itself was seemless and the on board staff were very friendly and helped stow my bag. The captain apologized for the late departure of only 30 minutes and kept us informed of how the flight was progressing.

Cons: Flight took off three hours late. After we boarded the plane, we had to sit on the plane for over three hours before we finally took off. When you’re on a flight that’s already 15 hours long, the last thing you want to do is sit on the plane for an extra three hours for nothing.

Excellent 8.0

Pros: The efficiency of having my boarding pass on my phone (Apple Wallet). The Kayak and Delta apps streamlined perfectly and I was able to check in and pay for luggage through Kayak! I just need to do better at checking my phone due to both apps sending me updates about flight delays and luggage locations

Cons: Lack of space from being confined to the middle seat but the passengers next to me were nice and the plane ride was over before I realized it.

Excellent 9.0

Pros: My flight from STX was delayed some 30 minutes. That made a dent in the 57 minutes I had to catch my Delta flight. Naturally we landed at gate A2 and Delta was boarding at Terminal 2 gate B9. Me with my knee replacement can’t run and my wheelchair was not in sight. Thank goodness I had a carryon with wheels. I was out of breath when I got to Delta and the last passengers were boarding. I started panicking and interrupted the ground steward who asked me to wait with a smile. I waited . So when I told them I was standby they waved me on after showing my passport. I couldn’t find my boarding pass. I was pleasantly surprised to get a seat in first class. I was so thankful. My first time. Good things come to those who wait! Thank you Delta.

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,
