Jet2 has apologised to about 100 customers whose holidays were cancelled due to a pricing error on its website.
Prices advertised online for holidays to the Hard Rock Hotel in Tenerife were too low and when the operator realised its mistake it cancelled the bookings.
Customers were given the option to pay the remainder of the full price to keep their holiday, but in some cases this was almost double what they had originally paid.
One customers told the BBC that she was asked to pay an extra £1,400 on top of the £1,800 she had originally paid.
A Jet2 spokesperson said: "On Saturday morning, some holidays to the Hard Rock Hotel Tenerife were incorrectly placed on our website that were not actually available. The holidays appeared for a short period of time and we removed them as soon as we became aware.
"Unfortunately, some bookings did take place in that short period and we contacted all affected customers, that same day, to inform them that we would have to cancel their booking and that they would be refunded in full.
"We would like to sincerely apologise for the disappointment and inconvenience that this has may have caused. We did act promptly to ensure that those affected were able to make alternative holiday arrangements as quickly as possible."
