Airline reviews

Pros: "The checking kiosk with luggage check-in, weight station and automated ticket printing for boarding pass and luggage tag. Security checkpoint was smooth and moving fast. All above have vastly reduced stagnant check-in line at the check-in counters."
Cons: "Need more properly trained ground crew at baggage drop point (which is also the previously check-in counter) to ease the line and expedite the check-in. Also need more notification billboard along the long line to better inform the passagers what to expect at the security checkpoint."

Cons: "Parents that check to make sure their kids are not obnoxious during the entire 6 hour flight."

Pros: "Very kind crew"

Cons: "It's a 6 hour flight and not even a sandwich? Food on boeard is for sale. Same with movies or TV shows."

Pros: "Crew"
Cons: "Comfort of seats. Too close together."

Pros: "Not a lot to say really from a positive, In Europe if we had to fly over 4 hours the airlines put on larger planes, this plane was small for a 6+ flight"
Cons: "Small plane for a 6+ hour flight, food is . sub standard, if you want to watch the onboard entertainment you need to do so from you phone or Ipad, you need their app installed first and flash player, if not your screwed. They allow you to download their flash player but it does not work."

Pros: "From beginning to end the United crew was friendly, engaging and helpful."

Pros: "Courteous crew. Smooth landing. My only compliant is that we have to purchase in-flight wi-fi. I find this unacceptable, especially because the airlines charges upwards of $80 for an Economy Plus seat and then one needs to $26.99 for wi-fi for the duration of the flight."

Pros: "this flight was not overbooked or even full - the first one I've flown on in a long time that had empty seats!"
Cons: "no entertainment systems in the seat backs"

Pros: "able to use a personal device for entertainment."
Cons: "Seats did not have power outlets and were very close together. I am not a tall person and still had issues with not enough leg room."

Pros: "The two people that helped."
Cons: "That United had NO remorse for our inconvenience and offered NO compensations."

Pros: "The fact that I didn't die."
Cons: "Seriously? We can't have at least a few channels for free? Or a least a few free movies to view? How can you expect someone to sit there for 6 hours and just stare out the window. We can't even get limited internet to text/email? $25 for a few hours of service? You guys are really running a scam for your passengers."

Pros: "Good crew. Very professional."
Cons: "Back seat in plane does not move- tough for long trips. Having personal entertainment means if you do not know ahead- no options."

Pros: "Delay"
Cons: "Delays"

Pros: "Great flight and crew"
Cons: "The lady diana that helped change my seat at the gate had a bad attitude with my husband. She ended up over charging him to change my seat. Then he had to wait some time to get it resolved. Her whole attitude before and after was just not customer friendly. Please change her shift cause she does not seem to be a happy morning person"

Pros: "Newark flight was cancelled due to mechanical problems. I returned home and Caught another flight the next day through Chicago, as I didn't want to spend the night in the Chicago airport waiting for a connecting flight the next day. The flight crew, United airport personnel, and TSA were all very courteous and professional."
Cons: "There wasn't enough gate personnel to help everyone re-schedule our cancelled flights. The waiting line was very long. All media entertainment had to be paid for in order to access it. Seats were narrow and uncomfortable."

Pros: "Not much lots of crying kids, fully booked, so no escape"
Cons: "It just sucked. Delta on the way to NYC was great and this one was awful."

Pros: "In Chicago (where we were rerouted), the gate agent let my party and me board early to ensure that my guitar would have overhead space."
Cons: "The crew in Newark didn't hold our plane to Seattle, which we missed by minutes. No one took responsibility, and it was a chore to walk a ways and actually find the kiosk where United agents would rebook our flights. I don't understand why we had to go to another location for this."

Pros: "Generic regular flight"
Cons: "Pay for all entertainment and screen was hard to turn off. Didn't have optional flight tracker"

Pros: ".same as above."
Cons: "Second leg was delayed an hour to replace an O2 tank in the back. I understand that things break, but waiting an hour for a "simple fix" is a bit much"

Pros: "I liked the direct option to Seattle versus a layover mid country."
Cons: "Boarding procedures seem to make no sense. I don't understand why airlines stopped boarding from back to front. I can't see how this "zone" makes it any faster. Entertainment was not free. I get having paid movies, but there should be some free options."

Cons: "Cramped, uncomfortable, new entertainment doesn't work."

Cons: "Charge for tv!"

Pros: "Boarding was fast, staff were friendly, even though it costs the direct tv is nice."
Cons: "Wifi was in and out and I paid for it, no free food, no free entertainment options"

Cons: "This is wrong. I should be reimbursed for the extra I paid on the Newark to Seattle leg. I booked for economy extra/comfort and got only economy (coach). And with no apologies, no explanation. also,,... The flight was delayed by > half hour (but this happens). However, the flight attendants were somewhat unprofessional in their language.and attitude."

Cons: "We had 6 hours flight and no TV on seats... 6 hours flight and not extra to drink or eat Then don't have long flights"

Pros: "I enjoy all of the amenities United offers and the staff service overall."
Cons: "I didn't like the difficulty with which I had to use such amenities(wifi) a 6 hour flight overall isn't comfortable."

Cons: "Everything"

Pros: "Arriving in my destination."
Cons: "Had to pay for my second bag, even though I prepaid for "the works." My carry on was already paid for in the prepaid package but since I decided to check it on my return leg, rather than carry it on....I had to pay $60 to check it.
