Travel season is fast approaching, with millions of Brits preparing to book flights to destinations near and far to enjoy some well-deserved time off. And while it’s an exciting task, travel experts at Travel Republic are warning travellers to be extra mindful as they go over their details when filling out booking forms.

Simple autofill errors, such as using a nickname or a minor typo, are increasingly causing headaches for holidaymakers, with one man’s trip to Germany completely derailed by a seemingly innocuous mistake. Will Hobson, a recent victim of this issue, faced a gruelling 12-hour delay and a £400 fee after being refused boarding at the airport. The cause of his frustration was a “minor” discrepancy between the name on his booking and the one listed on his passport.

Will had used his commonly known name, “Will Hobson”, when booking his flight, but his full legal name, as stated in his passport, is “William Hobson”.

“I had no idea a slight name variation could be such a big deal,” Will admitted.

“It caused quite the drama. I spent 12 hours trying to fix it, including writing an email in German and trying to rectify it with the airline.”

Unfortunately, despite his efforts, Will was quoted £400 for a name change fee in order to secure a seat on another flight.

And this issue is not unique to Will, as according to travel experts, any deviation from the name on your passport – whether it’s a nickname like “Rob” instead of “Robert”, or “Liz” instead of “Elizabeth” – could result in being refused check-in and expensive corrections.

“Most airlines require passengers to enter their names exactly as they appear on their passports when booking. Using legal names helps prevent ticket fraud and ensures only the intended passenger can use the ticket,” said a spokesperson for Travel Republic.

While autofill settings on devices are convenient, they often mistakenly input shortened or preferred names instead of legal ones.

The easiest way to avoid such complications is to manually enter your full name when booking flights and double-check all details before completing the reservation.

If an error is noticed after booking, experts recommend contacting the airline as soon as possible, as in some cases, airlines will allow minor corrections (such as fixing a spelling error) free of charge if done within a certain time frame.

However, if a larger discrepancy, like using a nickname, is identified at check-in, the cost of correcting the error can be hundreds of pounds.
