Adam Armstrong, 19, has changed his name by deed poll to Adam West to go on holiday - because it was cheaper than fixing a Ryanair booking error

A student changed his name by deed poll to go on holiday - because it was cheaper than fixing a Ryanair booking error.

Batman fan Adam Armstrong, 19, would have been forced to pay £220 - double the price of his flight - to correct a mistake by his girlfriend’s stepfather, who booked him a flight under the surname West.

But he avoided the cost by changing his surname by deed poll to West for free and by getting a new passport under the name for £103, The Sun reported.

Mr West and his girlfriend India Lomas, 17, will fly to Ibiza with Ryanair as planned next week.

‘Her stepdad got my name from Facebook but I had put it as Adam West as a joke, because he was the actor who played Batman on TV,’ he told the paper.

Ryanair said there would be a £110 charge for amending the name, but because his girlfriend was on a separate booking, the administration fee would have had to be paid twice.

The charge is supposed to stop people from re-selling Ryanair tickets for a profit.

Ryanair has previously been accused of luring customers with low fares but demanding sky-high fees for ‘extras’.

The budget airline has imposed charges for anything from checking bags into the hold – at a cost of up to £75 – to checking in at the airport at £45.

In April Ryanair announced it would slash average ticket price by as much as 15 per cent over the next two years, but admitted that new aircraft would see even more passengers squeezed on board.

Michael O’Leary, the airline’s chief executive, said the average fare could be as low as £26 by next year.

Ryanair expects to grow its passenger numbers and cut costs by using new Boeing aircraft that will have more seats and reduce fuel consumption by an average of 18 per cent.
