Wizz Air will restart amber list flights from three of its UK bases next month.
The budget carrier will restore 25 routes from Luton, Doncaster Sheffield and Cardiff.
Destinations span Spain, Greece, Portugal, Croatia, Cyprus and Bulgaria.
It comes after the UK government confirmed on Thursday (8 July) it would ease quarantine for fully vaccinated amber list arrivals from 19 July.
It means from 19 July, Wizz will offer 44 amber list destinations in total.

The additions to Wizz’s network, starting in August, include:
