Find Cheap Flights from Colorado to San Francisco

Cons: Food was mediocre. Some staff was friendly, some was NOT

Cons: Entertainment system was extremely poor. Need app to use it so I didn't preload onto my iPad but tried to use iPhone instead and the streaming was just so poor and kept freezing that I just gave up and read a book. Also selection should have included a lot more shorter programs that could be viewed on less than 2 hour flight eg lifestyle programs, news etc.

Cons: Seat space was very tight

Cons: I was traveling with two kids and they used my phone for shows and I brought another older Oppo phone for the myself. It just wouldn't work with the united app to open up the movies. Was unfortunate because I had two flights.

Cons: I did not like the lack of space.

Pros: THe passengers were well behave during and polite

Cons: The 2 hour flight delay

Pros: Wonderful service

Cons: We missed this flight because our earlier flight was delayed and all frontier would do is tell us that we could “google” flights on other airlines to get us where we needed to go. No hotel voucher for the forced overnight, no refund for the missed leg, nothing. I really don’t understand how this company is in business.

Pros: The seat was comfortable and the flight attendant was very helpful with all the questions I had, thanks for the wonderful first time flying.

Cons: Nothing give a 10/10

Cons: Nothing. Awesome Customer Service

Pros: The crew was very friendly.

Cons: The flight was delayed. A terrifying amount of turbulence the entire flight from Philadelphia to Omaha. I arrived later than expected.

Cons: Normal los azafato tienen que estar más pendiente ala tripulación que anda con nenes chiquitos los papas se se duermen y los salvajitos se creen que están en un campamento de verano.y quieren romper el avión más pendiente a eso

Cons: No problems at all!

Pros: Everything was on time & organized

Cons: I had to download that Gogo app to watch a move. That sucked

Cons: No meal option and my video screen volume did not work

Pros: Surprisingly comfortable for such a short flight. The approach is impressive. Friendly attendants and captain kept everyone updated when there was a slight delay. Was overall a really nice flight

Pros: Na

Cons: Flight delayed 11 hrs, they could not offer me an alternative to get me to my event in time so after five hours at the airport I had to return home. Their offer was "maybe" a refund and a $10 food credit. Out $500+ lost in hotel fees at my destination- which most importantly, was my ten year grad school reunion!

Pros: On time

Pros: It was a brand new aircraft in it was a big one.

Pros: The stuff were accommodating and fun

Cons: Power outlets worn out and won't hold a plug so they are unusable

Pros: Timely and comfortable

Cons: The prices of tickets

Cons: I was charged twice for my ticket

Cons: The stewardess was very hard to understand in English.

Pros: Ticket prices were initially really low.

Cons: Everything else about my experience with frontier. They nickle and some you at every corner. When you go to pick a seat that'll cost you $5-$25 per seat. Then you're looking at $35 per checked bag $40 PER CARRYON. The only time I have ever paid for a carryon bag. No complimentary water/beverages/snacks. The seats are hard plastic with very little padding and no reclining. The tray table is smaller than your average tablet. On our departing flight we sat on the tarmac for well over an hour with no explanation. Horrible customer service all around. I will never be flying frontier again.

Pros: I arrived safely

Pros: Same

Pros: Clean new planes and very friendly crew.

Cons: It got delayed on my inbound trip for over an hour and a half for no real reasons (all were excuses: weather, crowded landing at SFO, air traffic controller did not give the green light, etc.). On the way back we had to wait over 45 minutes for the plane in our gate to move out of the way so we can get in.

Cons: Notify us sooner about the 2 hour delay. Had to know there was not a pilot available.

Cons: The seats are so cramped - not just on this flight but on ALL flights. It’s especially hard on my husband who is larger than I am. Airline cre, food and entertainment made up for the space but US airlines should re-think this sardine approach to flying. Sorry to vent. Thank you.

Cons: I don’t understand the concept of the ability to use your mobile device for entertainment, yet not having a power source to charge your device.

Cons: Old aircraft ...what’s with the non-assignment of seats until the last minute unless you pay extra !

Cons: Worst landing ever .

Pros: Boarding was easy and organized.

Cons: Older plain with less leg room. Had to pay to watch a movie. Little bag a snack are little!

Cons: No on board entertainment unless you had your own device, which I didn't.

Pros: Flight was shorter than expected

Cons: Everything. The flights are constantly being delayed. Poor selection of snacks and beverages. If people are going to pay $3 for a can of orange juice. It should be a lot better than concentrate minute maid. There are no business class seats. None of the seats recline on the whole plane. Im still waiting for a voucher from a previously canceled flight.

Pros: I arrived at my intended destination.

Cons: They charged me for a CARRY ON which no other airline does or has ever done and they don't tell you until you're at the gate. It cost money to check a bag, so I didn't but it costs double to bring s carry on which seems like a manipulative, strategic move on their part. Awful frontier. Just awful.

Pros: Nice flight with competent crew.

Cons: Kiosks did not work for check-in so I had to queue up and wait for help. Then I got charged $45 for a carry-on. Not a great start to the day.

Pros: Nothing.

Cons: After building in additional fees paid for seats didn't really cost less than competing airlines. No reclining seats. First airline where you had to pay for everything including soda.

Pros: Friendly crew.

Cons: Slow boarding.

Pros: Flight attendants were great! We had rough weather for the entire flight, and they handled everything great

Cons: N/A

Cons: The pork dinner meal option was burnt … al the way through.

Pros: The plane was 2 hours late and I could not get home. Missed the connection to Greenville at 11:38. They told me there were no hotels in Atlanta and I would have to stay in the airport and then take the 8:55 am fight to Greenville. That took an hour in line and there was no help.

Cons: The pilot was awesome. He flew as fast as he could to help anyone make their connection but it didn’t help. But I appreciate him trying. Just frustrated that being military I didn’t get to board earlier or that they didn’t help me find a way home

Pros: Nice Hosts?

Cons: Cant watch TV for free- stuck watching gold rush whatever that is. Seats were uncomfortable knees felt cramped up smelled funny could not sleep, because the seats were not comfortable we sat at the gate for too long we took off late why didnt we de-ice beforehand? I dont understand why they say "we need to check your bags" when there is plenty of overhead space. It's stupid

Pros: I enjoyed my interaction with the other passengers.

Cons: Several delays compounded to make trip a lot longer and far less comfortable than it needed to be.

Pros: The crew and the fact that they at least acted like they cared.

Cons: After UA posted a four hour delay for my original flight, I switched to the next available 1.5 hours later. That flight got delayed and then delayed some more, and by the time I got to SFO, the flight I originally booked, landed about 20 minutes later.

Pros: Na

Cons: Flight delayed 11 hrs, they could not offer me an alternative to get me to my event in time so after five hours at the airport I had to return home. Their offer was "maybe" a refund and a $10 food credit. Out $500+ lost in hotel fees at my destination- which most importantly, was my ten year grad school reunion!

Pros: Great crew. Falafel meal was delish.

Cons: My seat was broken and didn’t recline. I booked first class bc of a bad back, so I count on that. Salad was wilted and gross. Plane didn’t have plug ins for phone! Entertainment system didn’t work well- movie kept buffering. Sky texting wouldn’t work either.

Pros: On time

Cons: Old aircraft ...what’s with the non-assignment of seats until the last minute unless you pay extra !

Cons: On time is always better, otherwise it was a good flight.

Cons: The crew was rude to the passengers. They charge form 9$ to 40$ for seat selection. Charge for a Carry on bag (anything that doesn't fit under your seat). The flights had maintenance issue, hence delayed. I will absolutely avoid traveling with frontier in the future.

Pros: Nothing

Cons: Crew members could have been more friendly, boarding could have been quicker, no compensation for extreme delay

Pros: Not to much

Cons: Was like riding a city bus. Even in row one didn't have much room to stretch out. Check in took awhile. Only thing they had going for them was good pilots and staff. But the planes are trash no entertainment, little selection of food and drinks. Don't suggest at all.

Pros: This was the last time that frontier receives any of my money.

Cons: All flights are late, always. Seat and luggage fees are much too expensive. Never again Frontier.

Cons: Delta put me on an aisle rather than window I am broad shouldered and got pummeled throughout the flight by passengers and crew passing by Gal next to me fell asleep on my shoulder It was ok. She was attractive. :-)

Pros: Yes the crew was amazing

Cons: Stop being LATE!!!!

Cons: Connecting flight to as delayed. And my dad was not able to get on the plane.

Cons: Nothing

Pros: Free movies on the included display and electric outlets are top notch.

Cons: I wish they would offer food service more in the middle as we just ate before boarding.
