Good luck.

They posted the miles. I think I got shorted the 10x for the actual flight cost in accordance with the bonus at the end of last year but I'll take this. I still hate how they call it a "one time exception.". I may still snail mail customer service in Denver to complain about the service I received. Yeah it sort of got resolved but only after them gaslighting me about taking the flight multiple times, weeks of waiting initially for no response and over a dozen emails/complaints. I just want someone at corporate to look and actually see what their outsourced CS does.

Here is the big part of their reply giving me the miles:

I flew last week and got my actual flight miles (no bonus for being elite), as did my travel companions. I did buy the ticket in 2023. I assume that WASN'T supposed to happen, and that we all are supposed to just get miles based on the price of the ticket (plus a modest elite bonus)?

If you bought the tickets in 2023 you get both the miles flown and the miles based on ticket price. It was a nice boost toward getting status again next year... I had assumed the bonus would only be for flights flown in 2023 when it was announced.

Well, that was quite nice on my $19 airfare. :)
And, actually, it will get my pooled account to 60,000 miles, which would get me 2 roundtrip tickets to the Caribbean. I haven't 100% decided on that redemption,but it would seem like a good use.

Just so people are aware of the timeline, I got a message from Frontier on Friday March 15 that the DOT has forwarded my report to F9. I had already resolved it but it shows how long it takes for the issue to be forwarded to them after a DOT complaint. The date I sent the complaint is in one of the posts above that I made concerning my issue.

So it finally happened to me: my wife and I didn't receive mileage credit for a Frontier flight earlier this week. I assume if it doesn't post in 3 days or so, it will never post? I initially didn't think it was a lot of miles (it was a "big fare" for me -- $39 -- and I don't remember buying it on an extra-miles promo). But, curiously, the flight does show in my "past trips" section of the website and there it says my "earned miles" are 2286! This is obviously a classic Frontier IT problem. Is there an easy way to ask for -- and receive -- 2286 miles? :)

Thanks. Pretty straighforward. How long has the processing time been?

They responded to me within 24 hours requesting confirmation of my info. I got back to them 15 minutes later.

36 days later and several follow ups, no response and no missing miles posted.

The only time I had a flight not credit was in January. I wrote about it in post #15. Even though I got it sorted out, I saw they responded to my DOT complaint after the fact as that wound it's way through the system.

Id file a report with DOT about miles not posting properly if you can't get it solved.
