Me 6’ 200 lb sitting in middle seat next to somebody that needed 2 seats for self (pls understand I’m not unsensetive nor prejudice just stating a fact). I requested to sit in last row (of both sides of plane that were empty but attendant said sears reserved for attendants - 2).

JAL is customer oriented and it's always a pleasant experience. Unfortunately, though the return trip is also JAL, the cabin crew isn't.

Mostly friendly staff and quick flight time.

Only half the plane got snacks and drinks. Additionally, I was forced to check my bag, which is a pretty big deal because I was connecting to an international flight and was unable to retrieve my prescriptions in all the rush to check my bag.

Best fligh I had in some time. Left on time, arrived early very attentitive crew (with smiles as they worked through the rear cabin - wish I had their names to give recognition for/to). Food rating should have had a ‘NA’ as I nor partner did not consume any food.

Can’t think of one thing - unless a flying saucer could have delivered me like in about 5 minutes to Cabo! Ok - maybe one thing: charging for a checked bag on international flight seems rediculous (you asked).

The service was prompt and professional. The plane on this trip was clean and in good repair. The snack was simple and tasty. It was a pleasure flying United.

The first flight from St. Louis to Chicago was very small. While I don't have concerns about flying in a small plane, I can imagine those nervous about air travel would feel concerned with the size of the aircraft.

Seats felt roomy, in comparison to many other regional planes.

Vinyl seats made my back really sweaty on a relatively short flight.

Completely missed meeting due to 6 changes made during flight - Ask for a refund of some sort and non was given - not even air-miles or ticket recognition. Customer service from United was almost non existent. Will not be flying with united ever again.

To be fair. The flight is only 50 minutes. By th time you get a drink it's time to land. It is completely unfair to the staff to have to do that. A flight like that. Have a box with a snack and some coolers that have 5 different beverages. I wouldn't even sell booze. I person can hold out for a flight that shot to get one on the connection or in the terminal.

It's always a cramped flight. Nothing to be done except use a bigger, more spacious plane. The good thing is it's the fastest way to get to Chicago from where I lived it would take 6hrs by car.

NOTHING!!!!!!

I booked a flight with them for the Thanksgiving holiday.... I was supposed to travel Wednesday 22 - Saturday to STLand back... I was IMMEDIATELY shocked by only being able to carry 1 personal item... When I found out exactly how small 45 centimeters was...I tried to cancel the trip & be refunded within 5-6 hours.... They told me to fill out a form & return it to them... THEY WERE SUPPOSED TO GET BACK TO ME WITHIN HOURS TO NOTIFY OF THE REFUND AMOUNT & NOT...I REPEAT NOT ACTUALLY CANCEL THE TRIP UNLESS I AGREED TO THE REFUND AMOUNT... I never heard anything from them! I just assumed it was just taking forever for them to approve my refund... Therefore...assuming that the flight was still booked...SINCE I never APPROVED ANY REFUND... I visited kiwi.com several times before the the trip & there was ABSOLUTELY NOTHING informing me of any trip cancellation... I went to the airport... Wasn’t able to board... Talked to kiwi.on the phone... Didn’t find out the trip was canceled until after the boarding was closed for that 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.

If you have more questions or if you have a bad price to report to us,
