You'll be fine. We've just come back from 10 days on the island....it's a pain to get there and back atm (Heathrow passport control tool 3 hours) but its worth it and I would fly again tomorrow without a second thought.Theyve announced today that they won't be adding ibiza to the amber plus at any point in the immediate future. Amber plus would be 5 days quarantine at home (if you test to release on day 5) it's still worth it for me.
There's 12 of us going over, 5 on Friday and the rest next Wednesday and we're all nervous but just going for it. If disaster strikes then so be it.
I'll be there for 3 weeks so as long as I don't catch it there, which I shouldn't because there's restrictions in place that prevent it, it should all be fine. I'm just wearing a ffp3 mask in the airport and on the flight
