A
7.6 Good
Pros:Everything was good except what I mention below. I would fly again, as your aircraft was clean, and the food/beverage packages had good options, I will just add additional bagage costs to the ticket price to make a determination of whether the flight is worth the price.
Cons:Paying for a carry-on. I would not have booked with frontier had I known I'd have to pay for the very small duffel I brought with me. I could have booked with Delta, had free beverages, and not paid for a carry-on, all for less than what turned out to be the total cost of this frontier flight. It should be clearly stated before booking that ANY bag brought with you would incure a fee. People would factor this into the purchase price and book accordingly.
A
4.0 Mediocre
Pros:The flight departed on time and arrived as scheduled.
Cons:I'm glad that I arrived safely because that is the one thing I can appreciate. The cheap fares equal the quality of the plane. Only 4 rows of 30 have reclining seats. It would be a stretch to say the seats are padded. The clientele is cheaper than the fare with lots of crying babes and impolite guests running to the door as the plane arrives to the gate.
A
4.3 Mediocre
Pros:Staff did a typical job, everyone was nice, nothing notable.
Cons:Frontier airlines is awful. With all the added fees, I could have just booked with Delta or another airline that at least offers their passengers water without charging for it. Or charging for my bag. What a joke. Not worth the "discount" at all and would never bother booking with them again.
