Generally speaking, there aren’t rules against having an airline ticket purchased by a third party. There are some specific exceptions, though I don’t remember the last time I’ve heard of such a requirement for domestic travel within the United States. That brings me to a very unusual story that has been shared with me…
Frontier refuses passenger boarding for strange reason
An OMAAT reader asked for my take on a situation that he just dealt with. He and his daughter were booked on a Frontier flight from Phoenix (PHX) to San Francisco (SFO) on December 7, 2025, with the tickets having been purchased around three weeks earlier. They booked using a friend’s credit card, since that friend had an Amex Offers deal for $50 off a $200 purchase, which they weren’t otherwise going to use.
A day before the flight, the traveler went to check-in online, but wasn’t able to do so. So he contacted Frontier’s customer support, and was told to bring copies of the purchaser’s ID and credit card to the airport, when checking in. As the reader explains:
I brought exactly what they requested, but airport agents said the purchaser must be physically present at the same airport with the original card. They confirmed via their internal line that verification at the purchaser’s home airport was not allowed. The supervisor also claimed this was “against the Contract of Carriage” and that Frontier does not allow tickets purchased by someone who isn’t traveling. When I asked for written documentation of the policy or reason for denial, they refused.
The traveler ended up having to book a separate ticket on American, and asks for my thoughts on whether Frontier’s handling of the situation aligns with published policies. He also asks what action I’d recommend he take, like filing a complaint with the Department of Transportation (DOT) over involuntary denied boarding.
For what it’s worth, I asked if there was otherwise anything unusual with the ticket, or any sign that things were wrong. He explained that everything looked normal until online check-in. He also clarified that a different friend purchased separate Frontier tickets for him on a separate trip in August, using the same promotion, and there was no issue at all.
I’m really confused by how this could happen?
Based on some quick online searches, I don’t see widespread reports of Frontier requiring that the information for the passenger and the credit card member must march. I also went through Frontier’s contract of carriage, and I see no mention of a requirement for the cardmember to also be the person flying.
If you are going to require documentation from the person who used their credit card:
- It’s important for the airline to share the correct details with the traveler about the documentation that needs to be provided
- It seems unreasonable that the verification can’t happen at any Frontier station, but instead, has to happen at the departure airport
I don’t even see what Frontier’s motive here would be. It’s one thing if we were talking about loyalty program fraud, or something, but we’re just talking about an outright ticket purchase with a credit card. Is there some other potential explanation here? I can’t imagine Frontier is directly tracking how people are using Amex Offers deals, so that wouldn’t make much sense to me either.
With that in mind, what would I do in this situation? Well, I think trying to bring some attention to this is probably the best thing that can be done. I wouldn’t expect much resolution in going through traditional customer service channels (most airlines aren’t great at this, and in particular, I’d manage my expectations with an ultra low cost carrier). Sure, a DOT complaint could be filed, but that’s potentially a long process, and I’m not sure if it’s worth the effort.
I’ll forward this to Frontier’s communications department, and see if they have anything to share. But otherwise, I’d like to open it to the OMAAT community, and hear what others think.
Bottom line
Typically it’s not an issue to buy an airline ticket with someone else’s credit card, especially for domestic flights, since it’s a common practice. However, an OMAAT reader had booked a Frontier ticket with a friend’s credit card, to take advantage of an Amex Offers deal.
He wasn’t able to check-in online, and was told he needed to bring a copy of the cardholder’s ID. He did that, but that wasn’t sufficient, and he was told that the cardmember needed to be present at that airport. Despite claims by the representative, I don’t see anything in Frontier’s contract of carriage supporting this.
What do you make of this Frontier credit card situation?
