Securing a coveted first-class seat upgrade on a flight is not as simple as bribing the crew or claiming a honeymoon, according to a flight attendant with 15 years of experience. Barbara Bacilieri told creatorzine.com that passengers frequently attempt such tactics, but they are generally unsuccessful.

Most decisions regarding seat upgrades are made hours before a flight departs, Bacilieri explained. By the time a passenger inquires about an upgrade, the airline's upgrade list, often prioritizing frequent flyer status, has likely already been finalized. "The crew simply follows the list provided by the airline," she noted.

Despite the emphasis on frequent flyer programs, Bacilieri suggested several strategies that could potentially lead to an upgrade, regardless of status. She advises checking in as early as possible when online check-in opens, rather than simply on the day of travel. For airlines where priority levels are similar, the passenger who checks in first may receive preferential treatment.

Traveling alone can also improve the chances of an upgrade, as moving a single passenger is easier than accommodating a family. While a passenger's attire is not a direct factor in upgrade decisions, Bacilieri pointed out that dressing smartly can prevent a passenger from being overlooked. "A suit isn’t necessary but looking neat and presentable can prevent you from being overlooked," she stated. Conversely, overly casual attire could potentially work against a passenger.

This advice comes amid recent discussions about passenger attire. A fitness influencer reported being denied boarding on a Lufthansa flight due to her outfit, which consisted of biker shorts and a sports bra. The flight attendant allegedly informed her that she was not wearing appropriate clothing for a public journey. Lufthansa representatives stated that passengers must wear clothing that is "appropriate to the character of a public journey."
