Find Cheap Flights from San Francisco to Colorado Springs (SFO - COS)

Everything. Maintenance issue. Debording in Austin. Seat confusion. Never again!

The crew was fine.

At no time was I made aware during my booking that I would be charged for a carry on. The total cost added $60 to my flight. I feel completely mislead. Customers also had to pay for water on the flight which was ludicrous.

the price for the trip does not include that you have to pay for Carry-on, which is an odd expense to passengers. Especially for shorter trips with the round trip the carry on charge would equal up to at least $60. Which would equal to another airline who is comparatively better especially because those airlines aren't worrying about charging the customers for every single thing. Additionally, Frontier isn't a participant of the TS-Pre Check program, which Frontier should advertise.

Everyone was polite and The airplane was clean. Even though we were very late every member on staff was kind, patient, and happy.

We were about 1 1/2 hours off of it original departure time. No one explained a thing to the passengers. We were delayed and when we finally got on the plane we waited a whole hour to take off. There was no information passed to us about how long it would take and our potential wait time. When it is time to check in, we had to purchase our seats. No where, when we bought tickets for this flight, did it say we had to pay extra money to actually sit on the flight.

Run-of-the-mill airline

$35 to check a bag. $40 for any carry-on that doesn't fit under the seat! $6 just to select a normal seat. They make you pay for all beverages or food except "complimentary water."

It was cheap if you don't have any bags.

Very old airplane, if you have any carry-on you'll have to pay $45, the crew wasn't really that friendly, the plane just felt old, like the oldest plane I've ever been on. It didn't take turbulence well, so we were getting knocked around the entire flight. They were offering 'free water" as if it were some big favor.

The crew was extremely nice. The plane seemed clean.

The seats were tight. Not much leg room. Very expensive to check luggage, $40!

After flying Frontier Airlines for the first time with my 4 year old daughter, I was pleasantly surprised with my entire experience. The staff was very friendly and helpful at the gates, the flight attendants were amazing and both of my flights arrived earlier than expected!!! I will fly Frontier whenever possible!!

No airline miles for flying with this carrier, but for the price of my tickets and for the savings it didn't matter to me anyways!

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

Less than impressive. First time with Alaska. Actual Alaska flight was great. Your regionals left much to be desired.

Snarky unprofessional attendants on the regional flights.

The time!!!
