Jet2 has become the latest travel firm to cancel all holiday bookings - with flights not set to resume until at least spring.
The airline said all flights will be cancelled until March 25, subject to government travel restrictions.
"Due to the ongoing uncertainty and travel restrictions caused by the Covid-19 pandemic, we have taken the decision to extend the suspension of flights and holidays up to and including March 25, 2021," a spokeswoman told The Mirror.
"We will be automatically cancelling affected bookings with a full refund."
"Our customers work hard and save hard for their holidays, and we are very excited to take them away on holiday again. For customers due to travel from 26th March onwards, we will provide further updates closer to the time as appropriate.
"We would like to thank our valued customers for their patience and understanding."
The move follows in the footsteps of Virgin Holidays, which terminated all flights last week to help curb the spread of the new Covid-19 strain.
It said schedules will be cancelled until mid-February, joining similar moves by Tui and Thomas Cook.
The companies said customers would be contacted about their future travel options during what Virgin described as "these extraordinary circumstances".
Thomas Cook said it will call customers to offer refunds or rebooking.
Tui said it was "cancelling all holidays in line with international travel restrictions". It added that said customers due to depart from England, Scotland and Wales would be contacted to discuss options.

The company said that customers due to travel from an English airport before mid-February, or from a Scottish or Welsh airport up to 31 January, would not be able to do so.
Those customers will be contacted "in departure date order to discuss their options", Tui said, which include rebooking "with an incentive", getting a credit note, or a full refund.
"Customers currently overseas can continue to enjoy their holidays as planned and we will update them directly if there are any changes to their holidays," Tui added.
