Nothing was good about this airline with the exception of the baggage crew that finally helped me in Washington Ronald Regan Airport

My flight out of Portland was canceled and it took hours to rebook. I had to fly American Airline to Washington DCA where I roamed the airport at 9pm looking for someone from United. The crew in Portland ME told me the gate person would have a hotel for me.... The baggage crew had to help me.

I never flew to Phoenix from Washington. I was held over at DCA for the night so I lost a full day of my vacation! Had to fly to Chicago and then to Phoenix. Was a total pain!!!

Arriving and calling someone to help me with the wheelchair was good. The women were so friendly and helpful. But when you're "stuck" in a chair and I arrived early, it would be nice for someone to check to see if you had to go the washroom. And I had to flag someone down to get me to the aircraft. No one came by and offered. But overall fantastic experience. I would fly porter again.

Wish their was more food on the flight. Even though it was a short one.

The cabin crew provided the most information out of the entire experience and were extremely friendly. I appreciate Dawn in particular. The lounge is nice when it is not so over-crowded. I appreciate some complimentary minor snacks and drinks; it certainly helped with the delay. What would normally be sufficient seating and power outlets became people tripping over each other with delayed flights.

The lounge staff were hard to find and not communicative about delays. The board only had 1 update to my departure time, which was 30 mins after the originally scheduled time, and did not update again until 25 minutes after that second time had passed. The lounge staff did not make an announcement until after that board update and even then the information was wrong. The one time I found someone to ask a question to, I was given the same information. I had no idea why there was a delay or what to expect and no way of finding out. It made coordinating next steps upon my arrival to my destination extremely difficult. The lounge is not particularly well-equipped for multiple delayed flights.

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.
