easyJet always get confused as to which is which when I travel with my son (who has same first name).
They almost can’t cope. Despite different ages, photos and middle names..
I was on an internal flight in India 4-5 years ago when a passenger walks on and then says to the bloke at the window seat in my row that he was sat in his seat. The guy already sat down pulls out his Boarding Pass and says, “nope, its’ mine”.
So the other chap walks down and gets the stewardess. She looks at both Boarding Passes. Turns out they both had the same name (both English too), so the computer had just issued a copy 🙂
Lufthansa did that to me 3 weeks ago. They issued my son and I the same boarding card and then (whilst we were going through security) cancelled my seat as a no-show.
I got all the way through the security before a stewardess doing a ‘where are you sat?’ check spotted it.
Was a tense few minutes….
