It was a good flight after we took off but before hand was just BS!

Mediocre 3.6

Pros: We arrived at our destination.

Cons: The crew was extremely rude and sexist towards a family with kids that were just trying to fasten their seatbelts safely. Instead of helping, they only got angry at the parents for not knowing how to get the seatbelts safely on their children. They repeatedly ignored the wife and kept addressing the husband as if she was not there. It was very uncomfortable to be around and seemed entirely unnecessary.

Okay 4.3

Cons: When we booked the flight it had a 2 hr layover, which we thought would be enough to transfer plans. When we arrived we had to pick up our bags to go through customs. United's method of helping customers recheck their bags is very poor. We sat an waited until the only 2 staff members working the recheck helped another customer rebook a flight they missed instead of checking bags of customers needing to catch a flight. Eventually we ended up having to run through the airport with all our bags from the international airport to the domestic airport and checking our bags in that airport because the lady's at the recheck desk didn't seem to know how to handle checking the bags in. Once we made it to the other airport and checked our bags there we had 5 minutes before boarding was going to close to make it through security and run to the terminal. Luckily, once we made it to the domestic airport the staff there was very helpful getting us on our plane. Although we did have to run to make it.

Pros: Absolutely nothing about this experience has been good.

Cons: Flight delayed 4 times as of 11:40pm, the flight was supposed to leave at 8:10. At this point we have lost a non refundable rental car reservation and a non refundable hotel reservation and not a single person at the "customer service center" could even offer an apology or a suggestion as to what our next option would be, given that we are meant to be at a wedding in the Denver area in the morning. The aircraft is apparently pulling up as I type this, but that doesn't negate the fact that we are now getting no sleep, and losing a significant amount of money in reservations because we will not arrive on time. Please advise and rectify.

Cons: Was flying from LA and the plane got to the Denver airport on time but had to wait 20 mins on the track for a diff plane to leave so our plane had a place to pull up. This made me only have 15 mins to board my connecting flight to Minneapolis. After I rushed to the gate, United told me that they had a smaller plane so 28 people had to take a different flight. How does that happen? The $500 voucher they gave me did not make up for the time I had to fly to Chicago to make another connecting flight to get to Minneapolis. This was my second flight in one weekend as I was flying for an emergency. Both times United switched its gates for the flights last minute so I was scrambling to get to where I needed to go. Never again.

Okay 5.3

Pros: The crew was attentive, professional, kind, and capable.

Cons: I purchased two snacks (cheese and nuts) and both were very stale and of very poor quality. Also, our plane was 1 hour late to depart.

Mediocre 3.6

Pros: We arrived at our destination.

Cons: The crew was extremely rude and sexist towards a family with kids that were just trying to fasten their seatbelts safely. Instead of helping, they only got angry at the parents for not knowing how to get the seatbelts safely on their children. They repeatedly ignored the wife and kept addressing the husband as if she was not there. It was very uncomfortable to be around and seemed entirely unnecessary.

Cons: The slow ticket machine :(

Cons: My flight is still delayed 8 hours after it was suppose to leave. Luckily I booked a flight on South West and am home. I'm sure I won't get my money back as they wanted to charge me for cancelling.

Mediocre 2.6

Pros: The flight left 5 hours late, spent a good 30-40 min on the runway, the bagage claim was never marked and announced after most people had figured it out, and they lost two pieces of our luggage. I guess that is good service, since the common standard today is being beaten bloody and dragged off the plane. I wish they had communicated the reasons for the delay, given accurate estimates, etc

Good 6.0

Pros: It was fast service!

Cons: They charged us for every laguage we had. They also charges for drinks!? Seats cant recline..

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.
