From Washington to Albania everything was great.

The boarding at the first flight from Columbus to Washington was the worst flight I ever had, peoples who worked there were really rude and disrespectful not to only me but to a few passengers especially a lady who worked at the ticket both.

Fast puddle jumper from CMH to IAD.

United has replaced all gate agents with contractors. It is abundantly clear. No stakes in customer service, these folks are just slightly above automated robots following scripts verbatim with poor skills speaking English.

United check in desk in Columbus was incredibly unhelpful and unfriendly. There was an enormous line that seemed to grow because the three people working the check-in blatantly informed those customers who asked for help. The was no concern for helping people reach their gates. I had to flag down a woman and actual shout down the counter that I needed help or I would miss my flight. The woman at the gate check also ignored a question I had at being at the correct gate. Once on board we were delayed for an hour because the plan was overweight. They asked for volunteers to get off the plane but never told us when the next flight to Dulles would be, or how we may be compensated if we got off the plane. I missed my connecting flight in Dulles and lost my luggage.

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,
