Find Cheap Flights from San Francisco to Philadelphia (SFO - PHL)

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.

Nice customer service, flight attends very nice and helpful

Overall all was good

I truly enjoyed the ride. The staff, ambiance and cleanliness of the plane was so inviting. I even enjoyed the safety presentation. Also, complementary wine makes everything better :-)

Neighbors were very loud. No entertainment on the flight.

Our extra leg room seating was fantastic. The crew was delightful.

The entertainment was just okay.

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.

I only happened to wake up at about 3am to see that I had an email from Virgin saying my flight was cancelled, so I had to get out of bed, call the airport, and sit on the phone with them for about 20 minutes. I did get transferred to another flight free of charge which was great, but it was annoying.

I paid extra to ride with you all rather than some of the other domestic airlines. Well worth it. I love the atmosphere in your planes.

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.

Give free movies!

-SEATS ARE COMFORTABLE, LIKE THE TVs. -BOARDING WAS EXPEDITIOUS.

-SELECTION OF ENTERTAINMENT WAS LIMITED. -SNACKS WERE EXPENSIVE.

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!

Both of my flights there and back were delayed. It wasn't like there was any weather issues..it was inconvenient and there was no heads up

What a great experience. Comfortable, mood lighting, efficient crew.

Not enough partners in their frequent flyer program

I had booked an international flight with British Airways and it ended up being American Airlines. There was no notification of this change and I was not happy. I found AA to be subpar. The plane itself didn't have individual screens and my view was obstructed by other seats. The food was terrible and I got sick later, possibly from the bad airline food. Overall I got to my destination on time, but unhappy as I had chosen an airline and was forced to use another.
