Up until the end of MAY 2022, you can amend you holiday date for free, as long as its over 28 days away. If your under this time frame, say 7 days to go, just tell them someone in your party has covid. You wont have to provide proof, and you can push back the date.
Might help a few people here waiting for there passports.
I’m thinking about using the covid flexibility route. I fly on Sunday and still no sign of passport. It also says on their faqs that if you have covid symptoms they advise you jot to fly and use flexibility plan 🤷♀️
Will let you know how I get on if it comes to that!
