Don't fly Frontier Airlines from San Antonio, Texas!

In Febuary I was flying Frontier from San Antonio to Denver and arrived at the ticket counter at 5:40AM for a 6:20AM Flight. No customers were at the counter and the [person] at the counter would not accept my luggage because I missed the cut off by 5 minutes. The TSA guy was standing by the X-Ray and was not busy. I pleaded with [the agent] and [was told] rules were rules and would not let me on. I went to the United counter for a flight 2 hours later and watched [the agent] while I waited putting on luggage on the belt and I yelled over, "Whose lugguage is that?" [The agent] said it was for the people who were on time. This was 5-10 minutes after I left the counter!! Frontier ended up giving me a voucher for the value of the ticket.

Last week I flew them again and this time I went 2 days early to exchange my voucher just to be safe. I am so glad that I did..it took 45 minutes to exchange my voucher because "[name of agent removed per FT TOS]" did not know what s/he was doing and s/he ended up voiding it and then reinstating it and then demanded more money for the ticket. I called Frontier and they sent me a $75 voucher...not good.

Flying out of Denver was a breeze but flying out of SA is a disaster...
