I could not change the time of my transportation and arrived 10 minutes past the check in deadline (an hour prior to the flight taking off). I was refused access to the flight and offered a flight 5 hours later. The staff was rude and not helpful. I had heard negative things about Frontier and now I know why.

On two of the legs of the trip they notice I was a tall person with long legs and upgraded me to seats with more leg room!! I didn't even ask. Thank you.

On the way back there were open seats with extra leg room and I asked the gate attendant if it was possible to switch my seat to one with more room and they said they only could if I paid extra.

Fortunately as a passenger the economy flight area was very spacious due to low numbers of passengers. Which provided a comfortable seating space.

The entertainment could and been a little more variable in the film range provided. But generally overall I had a excellent flight. Food was good. Crew were very good and I would definitely consider flying United on my next visit out and recommend that my family did. Thank you United.

Plane was old and dirty, seat pocket had junk in it. Seat was broken and couldn’t stay up. In flight movies were from few years back with a center tv and no head rest screen. Crew on overseas flights tend to be older in age and less tolerant..much better on continental on the same route.

Its a scam! They act like they are giving you a break by having you buy cheap flights but in reality it costs more than a bit more expensive flight. I had to pay $45.00 each bag no matter if it was checked or carry-on. In total round trip I paid $180.00 extra just for my husbands carry-on as well as mine. Must add that our flights together cost 286.00. We should of went with American Airlines. On top of that we couldn't select our own seat if so, we had to pay extra, so we had to sit separated from each other. It was ridiculous! Never Again with this company!!!!!

The boarding was delayed and the boarding area was crowded, Boarding was delayed due to high number of wheelchair passengers. I was seated in an Even More Space seat, yet was placed beside a woman who was obviously suffering from some degenerative condition, and was slumped over towards my seat. The result was that I was uncomfortable the whole way back to Kingston.

Our plane was defective so had to be replaced. This is fine, I certainly am willing to wait for a new plane if it means not blowing up over the ocean. The problem was how little the attendants at the gate communicated the situation to us. What should have been a brief layover became a 12 hour nightmare. The gate attendants did finally issue meal vouchers but they waited until 10 minutes before all the restaurants closed and only issued $10 a person. This is enough to buy a hot dog at an airport... We were told there wouldn't be any rescheduling of missed connections until we were "airborne". This resulted in mass panic and confusion upon reaching our destination. We were told to go to the service desk, half an airport away, but once the entire passenger contents of the plane arrived at that far flung service desk, we were mostly turned away to seek help at individual gates. This lack of communication meant I missed the next next available connecting flight and now have a further six hour layover. I understand accidents happen and planes can break down but the nearly complete lack of care and customer attention is, frankly, disappointing. I've now had nearly an entire day added to my travel time. If I'd been willing to loose that time I would have paid $600 less for my ticket. United finally offered a token of their appreciation : a $100 e-voucher. I have spent more than that on food and coffee in airports for the past two days while trying to survive until my next connections.

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.
