Aeromexico offered him a “free” flight change. Then it refused to give him one.

Jorrit Muller says his flight from Puerto Vallarta to Orlando fit his schedule perfectly. He had to be at a wedding early in the day, and flight 335 left in the early afternoon.

But it wasn’t perfect for Aeromexico. Three months before his departure, it changed its flight to one that left an hour earlier, during the reception.

“Had I known they would do that, I wouldn’t have booked that itinerary,” he says.

Here’s where things get frustrating: The airline made Muller an offer, but then walked it back, sent him chasing a refund, and then denied that, too. He’s out $700 and has nowhere left to turn except our advocacy team. 

Before I get involved, I want to know what you think. Should I take the case?

The offer that disappeared

Aeromexico’s notification told Muller that if the new flight did not work, he could move to another flight at no additional cost. 

So he tried. Through Aeromexico’s WhatsApp support channel, he asked for a later flight showing as available on the airline’s own website. That didn’t work because the flights he wanted were operated by Delta, even though they were displayed as bookable on Aeromexico’s site.

An agent then suggested he request a refund instead.

“Relying on that advice, and because the earlier reassigned flight was not workable, I purchased replacement flights operated by Delta at our own expense, expecting Aeromexico to refund the unused ticket,” Muller says.

Then, unbelievably, Aeromexico refused to honor the agent’s verbal promise. A representative told him that because the airline had offered a replacement flight, it didn’t have to refund him.

Muller filed a U.S. Department of Transportation complaint. The airline’s response to the DOT echoed the same point: A seat was available. It was a minor schedule change. End of story.

What the rules say

Under DOT rules, an airline must offer a refund when it makes a “significant change” to a flight. For international travel, that generally means a schedule change of six hours or more. Aeromexico’s change here was just one hour, which does not meet the federal threshold. By the letter of the rule, Aeromexico wasn’t required to refund Muller’s ticket.

And what about Mexican law? The country’s consumer protection agency is Profeco, and it enforces the civil aviation law. That legislation requires a carrier to compensate passengers for a flight delay, but those rules focus mostly on a day-of-departure problem. 

A delay of one to two hours might earn a traveler a small voucher. But an advance schedule change of just one hour doesn’t automatically trigger a full refund under Mexican regulations. So even if we look south of the border for a legal remedy, Aeromexico is likely off the hook for a mandatory refund based purely on the time shift. 

Profeco would probably view this case exactly the way the Transportation Department did—as a minor adjustment that doesn’t warrant a refund.

What Muller says

Muller’s argument is not really about the one-hour shift. It is about what the airline told him when he tried to reschedule.

He said the distinction between a cancellation and a schedule change was never communicated to him. When he looked up his original itinerary, the booking he had purchased no longer existed as an option. From his perspective, the flight had effectively been canceled.

“Even if Aeromexico now wants to describe it as a schedule change rather than a cancellation, the practical outcome was the same for us,” he said. “The itinerary we purchased no longer worked.”

He kept circling back to the same point: Aeromexico made an offer, and then wouldn’t honor it.

“The biggest issue for us is that Aeromexico expressly told us that if the new flight did not suit us, we would be able to choose an alternative flight free of charge. We relied on that,” he said.

When Muller tried to use the offer, he said no workable alternatives were available, even though later flights showed up as bookable on Aeromexico’s website. The agent then directed him to request a refund. He did, and Aeromexico denied it.

Muller said the airline’s response to the DOT did not engage with the most important part of the dispute, which was that Aeromexico did not stand behind its own offer of a free alternative flight, and that its own support agent told him to request a refund.

The advocacy team’s view

Our advocates looked at the case. Advocate Dwayne Coward noted that flight 335 was not canceled, but experienced a schedule change, which resulted in there not being enough time to meet his connecting flight. That would not trigger a refund obligation under federal rules. Aeromexico’s response to the DOT was consistent with that reading.

That’s a fair read of the regulations. But it does not address what an Aeromexico agent told a customer in writing on WhatsApp.

Honestly, this is a borderline case

The schedule change itself is not the strong part of Muller’s case. If that were all he had, this case would not be winnable.

The stronger argument is the one Muller keeps coming back to: An airline representative told him, in a documented chat exchange, to request a refund. 

That’s the kind of detail that can move a case from “the rules say no” to “the airline said yes.” Whether Aeromexico’s WhatsApp record actually supports that account is something I would need to see before getting involved.

There’s also the code-share wrinkle. Muller said the later flights he wanted were displayed on Aeromexico’s website as bookable, but the airline refused to put him on them because Delta operated them. 

If a carrier sells a code-share seat, that carrier’s rules should apply to the entire ticket. Telling a passenger that an Aeromexico-displayed flight is suddenly off-limits because Delta operates it is a finger-point of the kind that usually does not survive scrutiny.

Muller has done all he can. He has filed a DOT complaint, he has a credible paper trail, and as he put it in his last note to us, he tried to do the right thing and resolve it directly with the airline, but kept going in circles.

Should I take the case?

Here’s where I need you to weigh in:

Is a written instruction from an airline agent enough to override the DOT’s “significant change” threshold? Should an airline be held to what its representative tells a customer to do, even when the underlying schedule change does not legally require a refund? 

Or is Aeromexico right that the seat was available, the rule is the rule, and Muller chose to walk away?
