I was told that I had to gate check my bags which had all of the necessities to travel with my child ( snacks, books, toys) due to it being a full flight. When I boarded, there were still several overhead storage bins completely empty. Very annoying. The crew could have physicallt assessed and checked before assuming due to flight capacity.

I am muslim, but I forgot to arrange the kind of food I would prefer during the flight, and the gentlement I talked to said let me see what I could do to help you about it, and few minutes later came up with muslim meal. I was really happy! Thank you all again.

The flight crew was very welcoming and positive. They were attentive and ensures that every one had headsets, blanckets etc for the 8.5 hour flight.

Lacking food healthy food options. No salads or light bites available. The warm food that they did have was terrible and very salty. I wish their in-flight entertainment was not on our own devices because updates to the app are required which you wouldnt know unless you were on the plane and connected to their wifi.

The staff were fine, nothing really great, but nothing bad either.

So, we'll start with boarding. Why airlines can't figure out to board the plane from back to front is beyond me. No, let's load front to back so everyone has to uncomfortably shove past the people who have already taken their seats at the front of the plane. Then you get back there and all the overhead bins are full because everyone takes as many bags as possible onto the plane. Then you have to sacrifice the already tiny amount of foot room, "to put the bag fully underneath the seat in front of you." At this point you should be fine, except if you're over five and a half feet tall (I don't know if that's true I'm 6'2" and 275 lbs,) because then your knees are going to be buried so deep in the chair in front of you that the person up there doesn't even need a seat they can just sit on your knees. Luckily for you tall people, they put a nice metal rod just about knee level to really dig in and cause pain . . . Yay! Being a big guy, you try to be considerate and fold your arms in to give the person next to you as much space as possible, but don't expect that back as they'll spread out and become as wide as possible. Then to distract yourself from the discomfort, you try to use the free in flight entertainment via the United app, but "it's not available right now." In summation either be short and small or be rich and buy the seats with extra legroom when you fly United.

We have been on 6 flights over the last 8 days, all with Delta and we have already started telling people how wonderful the service was. Sherry on this last flight was amazing, working so hard all by herself as our flight attendant. We were very impressed. And the pilots all came out to say goodbye and thank you. All very nice...esp for me who needed some wheelchair assistance. We will certainly fly with you again in the future.

Smaller plane but ok for short flight

The check-in staff were very friendly and helpful.

I already knew I was going to pay $200 to ship my boards back home (I wonder if golf clubs which are roughly the same size cost as much,) but when pre-purchasing through the app for an "oversized" bag you have to put a "one" in the checked bag and a "one" in the oversized bag even though they're the same bag, but then they charge you for two, and when you tell the check-in person that you only have one bag of course they can't issue a refund. No, they tell you that you get to call customer service when you return home.

I was so pleased that United offered the flexibility to change my flight before the chicago snowstorm without incurring a change fee.

I paid for seats on my original flight. But ended up sitting separate from my traveling companion on the new flight.
