Did my first trip yesterday out of the UK since Brexit and since Covid. Went to Mallorca for a few days. Didn’t quite know what to expect but here in the UK and Palma, covid is over. No masks no distancing nothing so if you haven’t had it or are wary about catching - don’t fly!
As for entry into Palma, absolute doddle. Scan passport at auto booth like in the UK and for first time ever got a stamp when we arrived and a stamp when we left in the passport. Don’t care what anyone says, having the stamp in my passport made Brexit totally worthwhile
On a serious note though - I didn’t experience any hassles at all, no huge queues, no baggage delays, nothing at all.
