Pricey Tripped Up,

In March 2024, I used to be awaiting my $96 Frontier Airlines flight from Fort Lauderdale, Fla., to Trenton, N.J., when gate brokers introduced they had been in search of 20 volunteers to fly the subsequent day as a substitute, to be able to lighten the plane’s load. The supply: an $800 credit score for a future flight. (Or was it a number of future flights? This was the topic of debate amongst passengers.) I stepped ahead, and was requested to write down my electronic mail deal with on a chunk of paper, which was handed round for the opposite volunteers to do the identical. The gate agent was affected person and well mannered, however didn’t present me with any receipt. After I returned the subsequent day for my make-up flight, he was there once more, so I requested why I hadn’t obtained an electronic mail with the credit score, as different passengers had. He didn’t know. Later, I reached out to Frontier, however the provider made it very onerous to achieve a human by cellphone and despatched me emails that didn’t actually make sense. I did get a $384 cost — not a voucher — a couple of days after the flight, however since Frontier nonetheless owed me about $300 from a cancellation the yr prior, I assumed it was for that. Are you able to assist? Linda, Princeton, N.J.

Pricey Linda,

Let me get this straight: Frontier’s methodology for retaining observe of volunteers due $800 vouchers was to have them scrawl their electronic mail addresses on one piece of paper?

That’s a rhetorical query, since you emailed me the picture you snapped of mentioned sheet, which confirmed an inventory of 10 electronic mail addresses in all kinds of handwriting. That’s the place I began once I dug into your downside, writing to the opposite 9 electronic mail addresses to ask if they’d gotten their credit — in some instances for the a number of vacationers of their occasion.

Eight wrote again to inform their tales. All (besides you) had obtained vouchers, though three complained, unprompted, in regards to the scribble-down-your-email-address system, and several other grumbled that the vouchers turned out to be for one-time use. One, Dino of Fort Washington, Pa., managed to steer Frontier to separate his household’s 4 $800 vouchers into eight $400 vouchers.

With assist from the documentation you despatched, the responses out of your fellow passengers and a useful electronic mail forwards and backwards with Jennifer de la Cruz, a Frontier spokeswoman, I’ve discovered what occurred, and gotten you again as a lot as — or possibly greater than — you deserve.

Asking passengers to jot down their electronic mail addresses, Ms. de la Cruz wrote, is “not customary process.” As an alternative, gate brokers are instructed to search out the shopper’s reservation within the system, verify the contact data is right, and annotate it as voluntarily or involuntarily denied boarding.

The distinction is essential. Compensation for involuntary denied boarding — bumping — is ruled by U.S. Transportation Department rules, whereas airways can supply no matter they need to search volunteers. Your identify someway discovered its approach onto the involuntary checklist, which on this case meant you’ll obtain 4 occasions the quantity of your unique $96 ticket, or $384. That explains the $384 that Frontier refunded your bank card two days after the unique flight. (It had nothing to do with the 2023 cancellation.) Frontier has now despatched you a $450 voucher to convey the quantity to just a little over the $800 you had been promised.

Ms. de la Cruz additionally regarded into cash — $302 to be precise — you say you had been owed from that 2023 cancellation. She mentioned your native journey agent erred in what and the way a lot you had been due. It was not a refund, the spokeswoman mentioned, however a voucher, and value solely $54 after charges had been deducted. That voucher was issued in 2023 and expired three months later. (You declare by no means to have obtained it.)

As a courtesy, Ms. de la Cruz mentioned Frontier would ship you the $302, and also you informed me you obtained an electronic mail that promised $302, within the type of examine. (For a corporation that expenses you further in the event you don’t examine in by way of its app, Frontier certain makes use of a number of paper!)

You and several other different passengers, by the best way, gave kudos to the gate agent. Let’s give him the good thing about the doubt that he didn’t know the Frontier system — because it seems he didn’t work immediately for Frontier, however for Trego Dugan Aviation, a contractor. It’s a quite common association today — even gate brokers sporting airline-branded uniforms are sometimes contractors. This agent was even type sufficient to jot down his work electronic mail deal with so you could possibly observe up. Alas, your message to him bounced again, not the primary time on this story {that a} handwritten electronic mail deal with led somebody astray.

So what’s the lesson for anybody pondering of giving up a seat for a voucher? Be cautious of something a gate agent guarantees you verbally, and at all times politely attempt to get a receipt or different written proof. Ask to look at because the agent enters your data, and take an image of the display screen and the agent — with consent. Favor money over vouchers, that are practically at all times time-limited, and ask for a complimentary resort room in case your substitute flight isn’t till the subsequent day.

Some constructive information for potential Frontier volunteers: Ms. de la Cruz mentioned (independently of this text) that Frontier has since modified its insurance policies to make vouchers good for a couple of flight. That’s a great factor, as a result of as Megan of Doylestown, Pa., one of many volunteers on that handwritten checklist, wrote to me, “Spending $800 on a Frontier flight shouldn’t be simple.”

I’ll say, at the least in the event you’re simply reserving one seat. I performed round with the Frontier reserving web page and — consideration North Dakotans — you possibly can, as of this writing, get a last-minute round-trip flight from Fargo to Cancún, Mexico, with further legroom and checked baggage, for slightly below $750.
