The pilot needed to let down the landing gear to cool off the breaks mid flight. Next time, maybe give the flight a warning you're about to do that because that's pretty unsettling to hear that mid flight without knowing what's going on.

Paid for bag online and was charged again

I didn't really get anything on the flight but I wasn't expecting anything.

It's a low cost airline, but they are very upfront about it. I didn't think the cost of the seat upgrades or the baggage fees were unreasonable relative to other airlines. Having to pay $3 for non-alcoholic drinks like tea is way over the top, but that is their low-cost business model so I accept it "as is".

Wade, the flight attendant was amazing! Great personality and very kind

Would have been better if I could connect to entertainment. I was able to see what was available and then when in the air I was not able to connect to any entertainment the app on my two phones wanted me to get wifi in order to get to the service.

Frontier charges for everything. Even a coke is $3.

Mar 24, 2019

Frontier is very basic and not my first choice. Pretty sad choices to make a person chose Frontier. Many added unnecessary expenditures

Extra fees are onerous

Flight staff was great
