Find Cheap Flights from San Francisco to Cancun (SFO - CUN)

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.

We left right on time and arrived a little ahead of time. Both take off and land were smooth. Personnel on board very attentive and courteous

Flight fare does not include no amenities not even a sip of water. You have to pay

I paid Volaris extra to use the CBX bridge. They ate that money because our boarding passes did not have the information and we had to pay again. On the way home the Volaris agent insisted we had to pay the Mexican immigration tax as foriengers. However, Mexican law only requires it after a week and we were there for only four days. Then another Volaris agent said my aunt couldn't fly within Mexico with her Mexican ID. He insisted she needed a passport. This airline is either completely incompetent or robbing people. They don't even offer you water on a three hour flight.

TV on the plane

Delayed flight

I was vary unhappy about our flights being move around and also delayed with no one to communicate these changes in English. We did get a voucher for food but since the flights where delayed with little time in between we did not have time to use it. Also our bags not making it with us ended up being an inconvenience but thankful that you had them shipped to us. This was the worst experience flying ever.

Our plane had mechanical problems at a previous destination which caused a chain reaction of delays. We were supposed to depart at 11:59pm. We departed closer to 3am and arrived 3 and a half hours late. As I result I missed an appointment costing me $75. This is our second JetBlue flight this weekend, both of which had major delays and greatly hampered our trip.

Needless delays, poor communication

I spent 11 hours at the airport waiting to fly out to Nantucket. The entire time we were told the flight wouldn't be canceled. At 12am it was finally canceled. By that time there was only 1 seat left the next day to Nantucket. My flight the next day was canceled as well.

Everyone one was nice, plane was clean, nicest in flight bathroom I have seen

We were delayed 2 hours and our gate was moved twice. Due to the plane was late arriving to SF. Then when it got there,there was still another plane at our gate. We were given free in flight direct tv as compensation. But I think a discount on our next flight perchance would be more appropriate.

I liked the ice with the Diet Coke I recieved thanks

My knees jammed into the seat in front of me! The least amount of legroom I've ever experienced ! My flight was already 730$ I guess you expected me to pay 97$ plus more $ to have a satisfactory seat assignment, sorry I thought I paid enough already

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!

The flight departed and landed on-time. The crew was friendly and helpful.

The space between rows is very tight.

It was comfortable enough, clean, and the crew was nice. We landed on time and without any complications. It was a very good price.

There isn't any entertainment, and the food and beverages have an extra price, even the water.

I love the movies they have aveilable, help me alot for a 4 hours flight

Pleased that a snack and beverage were served even though the flight was only 50 min.

Aeromexico no longer has their own kiosk at the Atlanta Airport. Wandered around for 10 min looking for it until a KLM employee let me know I had to check in with Delta.

Boarding Check in was smooth and well organized by group number.

Connection in Mexico City Airport Terminal 1 is a nightmare if you don't know Spanish.

Direct flight, no layover

Not very comfortable seats

The interior of the plane was updated and modern.

We had a 6+ hour flight and nothing worked. No tv, no wifi, and no service.

The crew was wonderful. We accidentally left our Camera on the plane and didn't realize it until we got to our hotel. They had found it and returned it directly to our hotel. They saved our honeymoon.

We had checked in early and selected seats together because this trip was our honeymoon. We or an alert saying our plane was changed as well as our seats and we were seated on OPPOSITE SIDES of the plane. We were then charged over $200 in order to sit next to each other. I even called United directly and they said there was nothing they could do. That's pretty inexcusable and ridiculous. If the customer service representatives are not Empowered enough to rectify such an egregious inconvenience, then why do they exist?

Nice seating

Wait at airport under construction

The crew and staff were very nice and accommodating, so no complaints there.

I actually had a rather bad experience, but it was with the Mexico City airport, not Aeromexico. Honestly, no major complaints. Thank you.

The crew at the desk in sfo and Dallas were great

Waited on tarmac for an hour in hot plane medieval conditions . Crew blamed pilots pilots, pilots said it was conflict of scheduling?! How does this even happen?

No delays. No problems

There should be more free food.

The entertainment was awesome. Made the flight time go very quickly...

They put my wife and I in separate seats. Between strangers.... WTF

the smooth landing in the airport of the Mexico city
