Flight delayed since early this morning, another 45 min delay on the tarmac and the wifi went out midflight. It wasn’t the most bubbly flight crew either, sort of miserable.

They were very efficient on getting people on the plane

I had gotten sick on a flight....just a little and did not receive alot of help from staff as there was no bag for me in my seat. I had to clean up the area. I also found there was not spray if needed for this sort of accident. Other issue - which is just a general is people who bring the big suitcases and people who have smaller cannot get it in overhead due to the size. Also the fees for a second bag is ridiculous and it was unfortunate that I had to pay as if I did not then I would have been over. either way....lose lose

From checkin to in flight service. It was horrible. The 5 hours flight with nothing, no tv, movie, nor complimentary snacks or drink. Everything need to be purchased, even a small orange juice cup will cost about $4. The only free is a cup of ice water. When I asked for another water, they told me they only give 2 cups of 2 waters. If I need more, I need to purchase it. Omg! Really? I seriously think they hire those stewardesswith a minimum wage and they have to sale stuff for commission. Why would they need 5 stewardesses when they didn’t even serve.

Boarding was smooth enough

I'm a disabled person, I need an aisle seat for my long legs and busted knees, but the aisle seats had about 1/3 the space for feet as the other seats. My knees were pushing into the seat in front of me. Drinks went around once about 1 hour in to the 5 hour flight, but not again after that, though they came by to collect trash 5 times. Flight crew were polite, but some clearly didn't want to be there. This is the first flight I've ever been on where I was in tears from pain, and i felt like i couldnt ask for water or even the wheelchair I needed after the flight.

Brout my granddaughter's pack and play, which was not at my arrival ciry of LAX. It has been over a week and I keep getting told I will hear from them at COB. If it wasnt for me calling the airline, there would be zerp communication! I can't afford a new pack and play. Ugh!

When we traveled from LAX to VA, we had seats 4A & 4B, group B. When the flight attendants called people to board, they called group A first which isn't a problem. The problem was the group A crowd. Some of them put their baggage in our overhead bin. We should be able to put our luggage in the overhead bin above our seat. If not 2 bags, at least 1! I think ppl do that so their lazy butts won't have to carry their bags to their seats in the back. Please make sure attendants notice that there should be space for bags for ppl at their seats. Or seat the ppl in the back 1st and then seat the other 1/2 after. Thanks! Overall great flight.

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.
