MIA
PHL
Okay 4.8

Cons: AA flight into Miami delayed due to late arrival of aircraft, followed by significant delay on the tarmac waiting for another plane to leave. This then delayed getting bags that required rechecking. At the AA booth, even though I was 42 minutes before the flight, they would not let me check my bags (not 45 minutes before) requiring me to stay in Miami overnight before booking me on a standby flight the next day. Customer service representatives were unhelpful and supervisor was rude. As someone who travels a lot, this was the worst service I have ever received from an airline (which says quite a bit). Will rethink ever booking a trip on American again.

Okay 5.0

Pros: I think crew tried to make the best of the bad situation. Got to Atlanta faster than scheduled flight time and they were sympathetic. Don't really know about much else, as I slept the whole flight.

Cons: The 3 hour delay really cost us. Left Rome at 2:30 pm instead of 11:30 am, so missed 6:40 pm flight to Atlanta (so much for the 3 1/2 hour layover we were supposed to have). When we landed in Philadelphia, sat on runway for 45 minutes, waiting for gate. Next flight was supposed to leave at 8:40, took off at midnight.

Cons: My husband and I sat in row 30 (center & aisle). I sat in the center. As soon as the plane took off, we all heard a dog bark nonstop. The lady directly in front of me had brought a dog!! We felt terrible for the person to the lady's left and right. And then in the middle of the flight her dog pooped all over the floor! And the poor Stewardess' (they were SO wonderful) had to clean up the mess. Then the lady had to clean up more pee and poop and left all that mess right in front of my feet and handbag (which I put under the seat)! I had to hold onto my handbag and shoes the entire trip bc it was touching the pile of dirty paper towels! I couldn't eat the meal due to the gross situation, and I was very upset about this situation all bc of this one lady who had no regard for the ppl around her and behind her! I don't know what your policies are concerning bringing a dog on a plane, but it ruined my flight. I love Korean Air, and love the service and the stewardess' professionalism and attentiveness, but this has made me think twice about flying anywhere on Korean Air!

Mediocre 3.3

Pros: Nothing

Cons: I didn’t like anything about this flight, except that we arrived safely. I had the last seat, next to the toilet, and that container or whatever it is, was dirty. Every time someone flushed, I was bathed in the smell of urine. It was raining in Toronto; consequently, my checked bag was wet through. I’m glad I was coming home rather than arriving at a vacation destination, where all my stuff would’ve been wet. I’d like to see some effort put into keeping my bag dry. Also, the passengers had to slog through the rain to get on the plane!

YVR
LHR
Good 7.6

Pros: I’m not sure whether Air Canada has turned over a new leaf or Boeing built a better airplane. Maybe a bit of both. The ambiance is marvellous in the 787. The Flight attendants were attentive and thoughtful (remembering what I was drinking). We left snd landed on time. And the entertainment system is one of the best I’ve experienced.

Cons: I couldn’t properly adjust my seat. That shouldn’t happen on such a new aircraft. Other than that, and the fact I couldn’t sleep, everything was good.

Mediocre 2.0

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.
