Ryanair's random-seat-selection for passengers who don't pay to reserve seats is back in the spotlight.
It's after experts at Oxford University investigated the allocation system for a BBC consumer show.
Four groups of four people booked flights with the airline but didn't pay the extra charge to reserve a seat in advance.
When it came to taking the flight all sixteen had been placed in a middle seat.
Researchers say the odds of them all being randomly placed in the middle are higher than the odds of winning the UK's National Lottery.
Ryanair's seating policy has been in the headlines recently over claims the company is deliberately splitting up families and couples for not paying to reserve a seat in advance.
The company denies this and insists it hasn't changed its policy.
Responding to the 'Watchdog' investigation, the airline says " the reason for more middle seats being allocated is that more and more passengers are [paying for] our reserved seats... and these passengers overwhelmingly prefer aisle and window seats which is why people who choose random (free of charge) seats re more likely to be allocated middle seats."
