Flying is a more daunting and stressful time than ever, given Covid, ever-changing travel rules along with the usual tribulations of air travel.
It is fair enough if passengers are more edge, but an expert has revealed there are two simple words travellers should never say to flight attendants.
Willis Orlando, senior product operations specialist at the travel insider platform Scott's Cheap Flights, swears that there is a simple phrase passengers should never utter.
What are they?
In a new interview Orlando claimed the two words are: "I'm drunk."
The travel expert advised passengers should bear in mind that the consequences of saying those two simple words.
Getting intoxicated at 35,000 feet could get you kicked off board.
He told Yahoo: "Certainly a lot of us get very convivial with flight attendants and we want to pal around with them and make these kinds of jokes and we feel light-hearted—and maybe we make a joke about being intoxicated."
Flight attendants have the right to kick you off a plane if you're drunk, Orlando further added, saying: "They have to make a decision whether you're safe to stay on board.
"There are also things that they can do to penalise you.
"They could put you on a list of problem passengers—and this could all be misunderstanding if you make a simple joke."
The warning comes as international travel begins to resume, with more flights being operated by airlines across the entire globe.
