We'd usually be pretty chuffed with ourselves if we ended up with an empty seat next to us on a busy London-Dublin flight.
However, in the case of one recent Ryanair flight from Gatwick, an empty seat was reportedly not the only thing one passenger had next to him.
Noel O'Hare, a marketing student, boarded flight FR113 on Sunday morning, bound for Dublin. On arrival, he says he was greeted with a pile of vomit on the floor in front of the seat next to him – supposedly from a passenger on a previous journey.
He claims to have asked staff for it to be cleaned up, but was told this wasn't possible.
Taking to Twitter before take-off to express his anger, the 24-year-old posted a picture of the alleged offending mess, writing: "@Ryanair boarded flight FR113, looking forward to next 1.5hrs looking at vomit, was told will NOT be cleaned #filth."
Afterwards, Mr O'Hare told Mail Online: "It made me feel uncomfortable to sit next to and my attention the entire flight was directed towards the vomit."
He also explained: "I asked a male cabin crew member what was the mess was, he replied it was vomit and someone got sick on the previous flight.
"I asked is it going to be cleaned and he replied no, it would not be cleaned until the aircraft had reached Dublin."
A statement from Ryanair said the issue arose due to a shortage of staff at Gatwick – something which meant there was no time to have the aircraft properly cleaned.
"We sincerely regret this incident which was caused by a shortage of cleaners at Gatwick Airport, which would have delayed the return flight by more than one hour," they wrote.
"We apologise for any inconvenience caused."
