Find Deals on Flights from Chicago to San Francisco (CHI - SFO)

I don't understand why my TSA pre-approval is not included on a Frontier Flight. I have Global Entry verification, and am surprised this is not honored.

The price of the trip did not include a seat, nor baggage, this was unclear and I felt misled. The seating is extremely uncomfortable. Checking in online was terrible, the website was hard to navigate, the prices were inconsistent (I was checking on my phone and computer at the same time and getting different rates for seats). I felt the communication was poor. I did not feel safe. I will not choose this Airline again.

Everything else OK.

Sat on the ground for a long time after boarding.

FINALLY American has up to date aircraft!!! Five years ago half the seatbacks and lighting on long distance flights didn't work. Swore I would never fly them again. They have redeemed themselves. nice aircraft

Inflight movie questionable. Couldn't figure out wifi entertainment options from inflight magazine ( over 60) and staff too busy to assist ( though didn't ask - just could see they had their hands full with beverage service). Would recommend video instructions after preflight safety video for tech unsavvy travelers. Also reminder on reservation to bring your own headsets and electronic devices.

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.

-friendly crew, although they didn't really have much to offer other than Frontier credit card applications. I guess you get commission if you get people to apply? it was pretty strange. -they didn't lose my bag

-lights kept coming on on both red eye flights. -they woke me up to ask if I want to PURCHASE something to drink lol (I'm serious. this happened) -they charged me for airfaire, then to check in bags, then to buy a seat. (so I don't know what the airfaire bought me) -zero cushion in seats -zero entertainment. not even buying option for wifi.

No in flight entertainment. No free baggage.

Rude staff, uncomfortable, terrible bang for your buck

Boarding was easy. clean plane, crew was very friendly. I was very concerned though, when we banked left and did a complete circle in the air. An explanation from the captain would have been terrific. I made sure I was the last one to leave the plane and asked him about it when I saw him at the exit. He told me what happened but I would have liked to know while it was happening. Besides that, the coke and pretzels were divine. :)

coffee was horrible

upgraded return flight to get more room and reclining chair

flight attendants were on their cell phones, talked loudly with each other and acted unprofessionally the whole trip

Price and smooth ride

No complimentary drinks or snacks

boarding and gate agent were superb

temperature in the cabin was hot enough to roast a turkey

Seats, video and overall comfort are all very nice on the new 900's.

Nothing.

crew was great

staff from de-icing company failed to show, despite >24h of notice of snow; missed our connection baggage handlers destroyed suitcase

Row 19 on a 737ER is great for room, as long as you don't plan on reclining (I rarely do in a daytime flight)

A little overcautious regarding seating the cabin crew because of possible turbulence, but better safe than sorry, I suppose. However, it is a common occurrence on this particular leg, so don't board knowing you might need to take a "break" before you get to Atlanta.
