Find cheap flights from Chicago O'Hare Airport to San Francisco

Pros: The flight attendants at united make everything super easy. I'm an anxious person when I get to the airport but I know that if I have any questions the united airlines crew will take care of me. The pilots are amazing and airways land the plane smoothly.

Pros: We landed safely

Cons: 20-30 minutes on the tarmac to take off. 30 minute wait after we arrived at the gate to have United staff attempt to line up the jetway with the cabin door. United is really firing on all cylinders lately

Cons: Boarding/unloading

Cons: United flights always delay. Rushing to Airport with all the traffic delays only to be told the it will be delayed for 30 mins is unacceptable. This occurs every time I fly on United. Also reported that the power outlet is not functioning 3 times but nothing was done .. also huge delay getting out!!

Cons: We got moved to a bulkhead seat with no storage - this was after selecting my preferred seat and paying extra. We almost were moved out of economy plus but I noticed that the seat assignment had changed.

Pros: smooth fligh

Cons: being delayed an hour

Cons: Entertainment system Movie Streaming erratic

Cons: I paid for the entertainment and I had no sound. Flight attendant handed me a very full glass of orange juice from an awkward angle that I had to reach over my seat and back cussing me to spill a few drops on the passenger next to me. She wasn't thrilled and the attendant just walked off. I was really awkwardly embarrassed.

Cons: Very uncomfortable plane!

Pros: Seat was ok.

Cons: Didn't find out about the delay until we were almost ready to board. No planning.

Pros: Nothing

Cons: Everything

Pros: Yes

Cons: Yes

Pros: Most people were so relaxed and pretty easy going about the whole thing

Pros: Great crew

Pros: Everyone was nice and it went smoothly!

Pros: Super friendly crew and comfy seats. Will definitely book again!

Cons: Nothing I can think of.

Pros: Great service from check in to landing

Cons: None that I can think of

Cons: The flight was delayed and I was concerned about missing my connection.

Pros: Entertainment could not be turned off, so there was a moving screen all the time. Selection poor. Could not access flight info. Could only watch at specific times. Seat had a hard lump very uncomfortable.

Pros: The crew did what they could and we're professional and curious, but there wasn't a ton to like about this flight

Cons: The flight was delayed. Ok, that happens sometimes and it annoying but part of air travel. The real kicker was that once we were on the airplane, they announced that seatback entertainment and wifi were not working, so there was no entertainment on the 4hr+ flight. Additionally, because the seatback entertainment wasn't working, the ability to control your own reading light was disabled, so the cabin lights were left on the entire late-night flight, making sleeping quite difficult. I understand that sometimes these things happen, but there are ways to mitigate- the gate agent could've told us that there would be no seat back entertainment while we were waiting at the gate delayed so we could've downloaded something, but they chose not to for reasons I can only hypothesize. Combine all this with the terrible 3-4-3 seat configuration and you're left with a terrible experience. Will never take this particular flight from Chicago again. It was cramped and one of the worst flights I've taken in recent memory.

Pros: On mobile safari online checkin doesn't work. Customer service reps on phone incredibly cannot check a passenger in. I almost missed flight for this. Most uncomfortable seats I've ever had to sit it for four straight hours. Arm rests are hard plastic, seats don't recline, hard seats too. And it's not cheap despite discomfort

Cons: Old flight and I won't flight with em

Cons: Worst seats in any plane I have EVER been on (and I travel ALL the time). Those steel seats with 0 cushion have resulted in me having the worst back pain and being on bed rest for the past 3 days on severe pain medication with no signs of improvement. I will never fly Frontier again.

Pros: Bag charged

Pros: Great crew. Very professional

Cons: They only had 1 beverage service. I was in the business class and no food was given out. I asked for certain beverages and was not given them.

Cons: Boarding is not very organized.

Pros: Everything went smooth and was great besides the boarding.

Cons: Boarding seemed to take quite quite awhile, not sure what the deal was but once we were boarded they kicked it into high gear

Pros: Nothing

Cons: Everything

Pros: The crew did what they could and we're professional and curious, but there wasn't a ton to like about this flight

Cons: The flight was delayed. Ok, that happens sometimes and it annoying but part of air travel.

It was cramped and one of the worst flights I've taken in recent memory.

Pros: The crew was fun, courteous, and very helpful. The complimentary refreshments were slightly better than those offered by most airlines.

Cons: Our flight ended up being an hour delayed. The cabin during the flight was extremely cold, and the attendants finally gave my wife a blanket which was for first-class only because she was miserable. Also, the in-flight entertainment through their wi-if onboard was down for “maintenance” the entire trip.

Pros: The plane was large and roomy. The employees were great. If the amenities that they offered would have been working I could have possibly given five in every category.

Cons: The wifi and power outlets didn't work.

Pros: Flight was fine

Cons: 3 hour delay sucked.

Pros: When I checked in for my flight I was given another passenger’s ticket (very similar name) and my checked bag was then sent to this other flight destination. when I got to my gate (correct destination) I discovered the error. The gate crew worked hard to get my checked bag off the wrong flight and rerouted to my flight within 20 minutes of my flight’s departure.

Cons: Super uncomfortable seating, WiFi/entertainment did not work. Given 1/2 of a drink. Which would have been ok if the price of the flight had been really low, but in fact the flight wasn’t that much less than the other airlines.

Pros: Love the how comfy the seats are and the USB charging ports at each seat.

Cons: Airfi could’ve been better. It didn’t load any movies for me at all. I got frustrated and just went to sleep.

Pros: Average

Cons: Free carry-on bag and more leg-room between seats

Pros: I would like you don’t delay the flight and time.

Cons: It could have been better if it was on time.

Pros: Crew members were friendly and fun

Cons: Delay after boarding caused us to sit on plane at gate for over an hour with no explanation of why.

Cons: Boarding stated on boarding pass was 435pm and we didn’t even hear from a person until after 5pm for boarding ohh Th we wise everything was good

Cons: Very comfortable. Had all three seats. A lot of crying babies, but I understand the pressure in their ears make it very uncomfortable for them.

Cons: Late flight, minimal beverage service....on a four hours on a plane one would expect at least a second pass through the cabin with water

Pros: very well trained / polite and friendly employees, i was impressed

Cons: no snacks wtf i'm starvin here

Pros: I like that I remembered to bring 2 Xanax with me

Cons: What could have been better is if the plane was deiced and ready for us when we boarded, instead of having us sit on the runway for over an hour while the plane was deiced.
