    I STRONGLY recommend that you only use Frontier Air as a last resort for your travel. They have recently changed the way they do business and their new business plan is to hit you for a fee at every chance. Honestly I felt as though I had gone into a bad neighborhood and was getting held-up at every corner., They charge you for EVERY bag you take on the plane, you cannot get a seat assignment before the gate unless you pay an extra $8 fee, they even charge you $2 for water on the flight. One of the most humiliating things is that just before boarding the plane they demand that every purse, bag, briefcase and carry-on must fit into one of two different measurement devices and if it does not, they charge you $100 to check the bag!!! It took an extra 45-minutes for everyone to line up and go through this humiliation. Mothers with children were trying to manage, an older woman got confused. Really, just for a few more dollars. The flight attendants HATE the new rules because it makes the passengers MAD and they blame the flight attendants. Not the attendants fault of course, but I can understand the frustration. So, be smart and use your dollars to vote for a better, less greedy approach. I say this even if you pay a few dollars more up front, because in the end you will probably NOT save anything on Frontier.

    Flight delayed two hours, then once on plane sat on tarmack another two hours......all over the dinner hour and they never offered free snacks! They still expected us to pay $5 for a bag of chips! Later they said we could get flight discount vouchers on their website. But food when I was starving would have been a lot nicer!

    Terrible check in process. Had no bags but could not check in at kiosk because of Midwest Horizon partnership. Had to wait in loooong line to check in with Horizon agent for both flights. Reservation would not come up on computer. BAD!!!!

    The flight was on time leaving and was early arriving in Denver, the gate was full so they went to another gate do not to negate the early arrival.

    We were connecting at SFO from Cabo. Our flight was delayed 1hr 45 min. It was to be a 1hr 59min flight but we ended up taking 2hr 35min. We finally got to DEN at 12:20AM but then we had to wait until 2:20AM for our luggage to show up on the carousel. The flight was long, cramped, bumpy, late and inefficient. One of my worst travel days ever.
