This leg home had nice United staff but bumpy. I got seasick but the cabin folks were kind. The leg out in a small plane was bad with one surly female cabin aide. I will tell United in a separate correspondence.

Missed the lufthanza flight by 5 minutes. United should have coordinated to have Lufthansa wait for 6+ passengers making the same connection or should have had an airport cart expedite us across terminals and gates to make the flight.

My flight was delayed leaving Pittsburgh and my connecting flight was delayed as well heading to Boston. There were no apparent weather issues so the delay was surprising.

Entertainment, and leg space.

Full plane, long wait to use lavatory. Crew was good, but should have upped their game under the circumstances, especially with regards to keeping the lavatory clean. The noodles for breakfast turned out to be porridge, and went straight to the waste basket.

Poor 0.0

Recent airline corporation consolidation has greatly reduced consumer choice. The surviving major airlines, in their effort to cut costs, sacrifice quality control and assurance. Pittsburgh's status as "no longer a major hub" was on full display here. United needed to have customer service agents available on site, but they did not. The review could easily turn into an essay on United's complete failure (ask the remaining passengers who were supposed to be on the PIT-IAD), but such a review would not change the state of affairs in the airline industry. I will be contacting United reps to lodge an official complaint.

Improper handling of situation. There was flight scheduled later, but CS agent kept jerking us around. By the time I reached the United counter, the next flight was full. My total flight time was 36 hours. I still can’t believe that the pilot was missing. Worse yet, the agent at the gate could have made things much easier instead of telling everyone that a pilot was on his way to the airport.

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.
