Unexpected delay for take off after being told the flight was going to be on time. They couldn’t give us a reason or an eta on take off while waiting at the gate which affected my ride situation once I landed in Seattle.

I began asking for my wheelchair escort the minute I got off the plane. I was assured in Houston they would be there when I got to Detroit. They were not. The request was clearly spelled out on my boarding pass along with my personal oxygen equipment information. I kept asking different staff and they would call for me then say somebody would be there. I waited for an entire hour and only when I started to cry did somebody do something. It was terribly stressful.

I did not like the attitude of the obese old man (I, too, am an obese old woman) as I saw it toward some of my cabin mates.

Thought the flight may have been delayed due to issues with ice rain in Toronto. From what was said, it wasn't that, some other issue with the plane and a cancelled flight in the west. No email in advance, no apologies, no freebies (like even a stupid sandwich). You sit an extra 2 and a half hours in an airport with a 5 year old before a 4 hour flight, and see how much the lack of anything grates. And paying for the first bag on the flight. And the emails they did send were after we were already at the airport-in no time to do any good. I Usually like West Jet , but losing my faith in them. Wonder how flair is...

Everything is good except our lunch as described below.

They ran out of chicken breast in our lunch packages, so the stewardess went back to get it. After 10 minutes she still did not show up, we turned on the help light, and still no one came. Finally she passed by and we reminded her the 2 chicken breast lunch packs, she said : "Sorry, I've forgotten about them" and ran back to get them for us.

The in flight staff was very friendly

Our 2nd flight was changed by the airline, causing us to have a 6 hour layover in Philadelphia instead of a 2 hour layover. Then when we ask about changing to a different flight they told us that the original flight we were supposed to be on (that we booked over 8 months ago) was completely full so that’s why we were moved, and there were no other flights available to switch to. So we accepted that. But when we printed our boarding passes, we saw that our seats were now separate from each other, and they were both middle seats! I don’t understand how booking my tickets so far in advance still resulted in these issues. We were finally able to get an aisle and window seat (not near each other) but both flights had poor to little entertainment, which I wouldn’t have expected on such long flights with American Airlines. Really was letdown. :(

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.

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.
