Find Cheap Flights from San Francisco to Chicago O'Hare Intl

Pros: Extra $60 for carry on bag, no tsa pre-check, uncomfortable seats which don't recline, no free beverages, no entertainment system, extra fee for selecting a seat or you're stuck in the middle without room to move or stretch. It's the last time I fly Frontier if another even slightly more expensive option is available.

Pros: The referee was delayed by over 4 hours due to avoidable maintenance issues. Not acceptable!

Cons: You definitely get what you pay for or maybe i should say you get nothing. My flight out was delayed 4 hours. Then my return flight completely canceled due lack of crew. Do not fly with this airline. It will end up costing double

Pros: There was, surprisingly, more leg-room in the exit-rows than I've seen on many other airlines.

Cons: Charging for the checked-in baggage is bad enough, but charging more for the carry-on bag? I could maybe understand charging fees for every customer interaction (a fee for changing ANY part of the customer's name after?) for short-hop trips, but not for flying across the country.

Pros: Normally a kayak super fan

Cons: Missed first leg of a return flight to london. Was given no options for rebook and my RETURN flight was also cancelled. Iberdola flight operated by American, ticketed by airfare.com. I've never heard of a product where you have to consume one piece in order to be allowed to consume the other you already bought. Legal basis seems very suspect. Do not fly with airfare.com and be wary of kayak vendors unfortunately.

Pros: Plane was on time. Free check of carry-on.

Cons: Seats are too cramped and extra cost for better seating sucks.

Pros: Seats are fine but confining.

Cons: Need more overhead luggage room, more seat room, missing individual monitors to watch a variety of programs.

Cons: I was sitting in premium economy and there was no food left. Unacceptable on a long flight. Also on long flight they should give you the can to drink. One little cup of liquid and NO food not even a bag of pretzels or cookies was offered. They could have at least come around with water only later on

Pros: We didn't crash?

Cons: After much concerns and inquiries made bag did NOT make the plane! There is as no one to h love me to n white Planes for 45 minutes! No one at the counter? Wow! Finally supervisor Jill was able to track it down in Chicago where th y took it off the he plane as my carry on because they had no room l ft from the h limited space. After working very hard to get my bag of o White Plains that evening, supervisor Jill hung out an hour past her shift ended to get it on the last transport to my hotel. The transport blew herself by ft and never showed up or called the o say he wasn't coming back! I got my bag on he next morning just in tim for my event! I also was not credited my frequent flyer miles. Some glitch in the system. Overall I must rate my experience as a one star simply because the pilots got us there safely.

Pros: *They offered a few snacks (small bags of cookies and water) during our 2 and a half hour delay. *Staff was friendly.

Cons: *Over two hour delay * No organization between the three boarding classes (3,4 and 5) so people just pushed to the front and stood in the way. *Overhead bin space was limited. *The inflight entertainment never worked.

Pros: Fun introduction of crew and local trivia sets the time for an enjoyable flight.

Pros: The fact that it was a large 777! Those just feel safer.

Pros: The ticket cost is slightly cheaper than other major airlines, but you have to pay for everything, including carry-on. Include them in your ticket price and you will end up paying more!

Cons: They charge you for everything! Uncomfortable seats

Pros: The people were friendly

Cons: Bering charged for carry on and for snaks

Cons: Great experience but for the exorbitant bag check rates

Cons: Apparently the seats are "pre-reclined". What a joke! My gf and I now call this Frontier Airplanes, because this can't be an airline.

Pros: There was an incredibly large passenger next to me and I was essentially afforded only a quarter of my seat. It is not really fair for anyone to have to sit next to someone taking up twice their seat.

Cons: Better allergy aware food.

Pros: the video controller in the headrest of the seat ahead of me. you could see the flight pattern, speed, temperature outside and other specs, which were interesting.

Cons: once again, the delta crew does not maintain their planes properly. during the taxi stage to get to the airway to lift off, there was a horrendous growling sound coming from the plane............seems like their hydraulic system is not maintained very well at all and it made a howling sound throughout the plane all the way to take off! we were wondering if there was something wrong with the plane.

Pros: There were a few hiccups with the overall flight process, but the crew was very friendly and informed everyone in a timely manner of the situation. There were also good snacks. Also, flexible baggage policy, which was great.

Cons: The boarding situation is odd and less organized or structured than any of the other airlines I've flown with.

Pros: Should have booked AA instead of BA.

Cons: AA couldn't find BA reservation. poor integration of services

Pros: The flight was great. Lots of movies to choose from. Food was pretty good too.

Cons: They moved our flight around multiple times. We first had a layover in Chicago then through multiple emails and one phone call they just flew us straight to London with no layover. It all worked out it was just stressful not knowing exactly when we were flying out and if we were going to make our connecting flights. It did work out and we did make it.

Cons: N/A

Pros: Customer Service was acceptable.

Cons: Flights were cancelled and bags were lost!

Pros: hospitality

Cons: Its an old flying piece

Pros: Flight attendants were excellent... Good humored, fun, good at helping rowdy people settle down... Happy we got to carry on food in addition to our single personal item. Boarding the plane was much easier with so few people trying to take oversized carry-ons onto the plane.

Cons: Being nickled and dimed for everything... seat assignments should come with the ticket... Tray table? really? Needs another name... tiny shelf? I'm small... so I fit in my seat. The guy in the seat next to me took up some of my seat, too... And he was normal-sized...

Cons: Flight was canceled and they didn't have any more flight Ha for 6 days. So frustrating. Ended up paying $500 for a last minute flight on another airline.

Pros: Boarding was easy.

Cons: all economy seats are in a fixed position and do not recline. In order to get a seat that reclines you have to upgrade for an additional $50 per seat. Non-reclining seats are OK for short hops but are extremely uncomfortable for long hauls.

Pros: Nothing.

Cons: Paying to sit next to my husband, delayed, got in late and had to sit there for another 45 minutes so instead of getting off at 7:30 it was about 10:00. Crew was rude and pushy and the tray tables were half the size of normal airplane tables.

Cons: did not like that Frontier charged $$ for seat selection before check in at the airport. There was no option for seat selection at $0. All options cost $$ - or you had to wait till airport check in.

Cons: It was seriously delayed

Cons: The flight was dirty, uncomfortable and the flight attendants were rude and looked sloppy. I will NEVER fly on frontier again.

Pros: not much

Cons: boarding process was a disaster. no one knew what they were doing. $30 for a carry? seriously? No free snack on the plane. Everything cost $5-$10... never again will i fly Frontier.

Cons: Always delayed departure. Poor plane condition

Cons: The flight was dirty, uncomfortable and the flight attendants were rude and looked sloppy. I will NEVER fly on frontier again.

Pros: flight takeoff and landing on time---- waited 35 minutes for bags
