Sat in the airport waiting for my flight for 5 hours. Finally got on the plane only to be thrown off and told that my flight was cancelled. Zero customer service. Nobody spoke to us. Just the worst

3+ hour delay on a direct flight is never ideal.

When I was boarding my departure from Raleigh to Orlando I was inappropriately scolded by a female dog named Mia because I didn’t pay in advance for my carry on bag ($75). Frontiers website is confusing regarding pre-paying for carryons so it was a simple mistake. I also had paid for “upfront plus” meaning me and my son were seated in the front row with no one in the middle seat ($450 upgrade). When we were boarding Mia said “sir, you didn’t pay for your carryon” in a not so polite tone and told me to get out of line and come back to the counter to pay for my carryon. The way they had the retractable rope left me no room to circle back without making the people behind me move so I just stood there and then she said a second time “sir!! Go pay for your carryon” in an embarrassing tone. I then moved their rope so I could get back to the counter when a second female dog then asked “are you done!?!?” because I had said “do you want me to bulldoze the people behind me?” I then said you do realize I paid over $400 for upfront plus so I was certainly not trying to sneak a carryon bag without paying. Long story short, I am soooo done with discount airlines!!! By the time you pay for all the “extras” you might as well have paid for Delta Southwest or American! Frontier airlines sucks and I was embarrassed by a female dog named Mia!!!

I know Frontier is a “no-frills” airline. I understand the concept. However, I jumped on some tickets for our family vacation, expecting to play a bit of a game to figure out the family bags and not over spend. In the end, I got the short end of this deal by far. 1. I did not expect them to charge the baggage fee for each direction. It makes the fee look high-ish at a glance, but reasonable. Then when you get to checkout and realize you have to pay it twice to come home with your luggage, it becomes ridiculous. 2. The low checked bag weight limit. I am used to packing a 50lb bag with my preferred airline. Frontier’s artificially low 40lb limit more quickly triggers the extra weight fee, which almost DOUBLES the price of the bag if you go over ($79 for the bag/$75 for the next 10 lbs) 3. The fee for a carry-on bag is the same as a checked bag but with a lower size and weight limit. Make it make sense! 4. The seats are terrible. My 2.5 hour flight almost had me losing my mind. I’m 6’3” and my femurs barely fit in the space provided. My knees had to wiggle just right to jam into the crack next to the armrest of the seat in front of me. The cushioning was thin and inadequate. I am tall but I’m not a freak. These seats are unacceptable. 5. I overheard the woman next to me speaking with the gate agent about being charged a $25 fee for not checking in online - she checked in at the airport counter when she arrived. That’s ridiculous. She was old and in a wheelchair. She had a paper boarding pass, and was obviously not tech savvy. She should not be punished for that. 6. They do not have good placement in the terminals. It was always out on the end or down on a subfloor, and we had to walk out on the tarmac almost every time. In Denver. Their home airport! 7. Every time I loaded a new page on the website while buying my tickets or my bags, it was constantly trying to upsell me on some esoteric bundle. Like, a pop-up every time. Very annoying. 8. No screens in the boarding area (at least where we were) to confirm you’re in the right place. Just static gate number signs. I am sure these are standard practices for Frontier, and I should have read more about them before I purchased tickets, but as a result of this single round trip, I do not plan to ever use this cut-rate airline again. I would rather pay the normal amount for a ticket and be treated like a customer instead of a mark.
