There was a delay from Charlotte to Dallas but not too much so it was fine. Once we arrived in Dallas, however, it took an absorbent amount of time for the crew to open the door. On top of that, the skyline in Dallas was broken down and it caused me to miss my flight completely. I’m a student so I don’t have much money so I had to “sleep” in the airport because I couldn’t get a hotel voucher due to the fact that I missed my flight due to the airport and not the airline itself. My next flight is tomorrow morning but now takes away time from an incredibly busy and tight schedule that I was on. Not happy at all with the Dallas airport.

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!

Flight was on time. Friendly crew.

It turned out that we were on stand by (without anyone telling us until the morning of the flight) and did not know if we were going to fly out. We could not select any seats at check in and only found out our seats a few hours before the flight. It was quite unpleasant and stressful as my husband and I were flying with our two children and faced a real possibility of not being able to sit together or getting bumped off a flight all together. It was a code shared flight between Lufthansa and United and each airline kept sending us to the other to get any answers or help. neither were helpful. It made it for an extremely frustrating experience.

United made me check my carry-on and would not transfer , so I had to wait for it and missed my connecting flight. Then I rebooked on a later flight which was cancelled due to weather. So needless to say I did not get to Ottawa and had to purchase a hotel room in Newark. United is telling me I may not get on another flight until tomorrow night. I am very disappointed.

They let me know they couldn't get it together enough to get a plane in an almost timely manner. Once they did I couldn't take advantage of the alternatives without risking missing out all together

The 4 plus hour delay that meant a 3 plus hour layover because of the missed connection. Requesting an agreement to just make the new connection because of their non-weather related delay.

Actually pushed back from gate on time in Philadelphia. Took about 25 minutes from then til take off. Landed only a few minutes behind schedule. Crew was pleasant. Food was okay.

It was a Finnair flight but operated by American Airlines. I booked through Justfly.com and paid extra for what I thought were our seats. Don’t pay Justfly for seating choice as the operating airline can switch your seats. Online checkin was difficult as I tried Finnair first with no luck, then got somewhere with American. Seats were not very comfortable but I guess that’s what you get in economy.

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.
