Some UK holidaymakers are concerned that they will be banned from EU nations because Spanish police are not stamping their travel documents amid airport chaos.
Following Brexit, UK passport-holders must have their documents stamped on arrival and departure from EU-Schengen nations.
This is because there is now a limit on the amount of time that you can spend in countries like Spain, with UK citizens allowed to spend 90 days out of every 180 in EU nations.
Holidaymakers fear that the rushed and stressed police are trying to get passengers through security quickly to quell queues, but in doing so are not providing the vital stamps.
This leaves holidays unclosed, and while you may have returned home from a trip, your passport could suggest otherwise leading to a possible undeserved ban, Wales Online reports.
One passenger reported having two entry stamps still outstanding - even though one was from an April trip to Ibiza.
The passenger said: "I now have two 'un-closed' Spanish visits in my UK passport, making a nonsense of the 90-day rule, and running the risk of me being accused of overstaying my rolling 90 days’ allowance. Which I haven’t."
Another traveller on a flight from Bristol to Majorca claimed officials were only checking the status of around one-in-10 visitors arriving on the holiday island, with just three officers on duty to receive incoming passengers.
The Majorca resident said: "The lack of checking of documents was obvious. They checked about one-in-10 and let everyone else pass on through."
A journalist who visited Majorca, and did not get his passport stamped on departure, was held up for more than an hour at Frankfurt airport in Germany because it appeared he had exceeded his 90-day allowance in the previous 180 days.
He said: "Luckily I had documents confirming I had left Majorca well before the end of the 90-day period. But it took time to convince the German police, leaving others I had travelled with waiting for me to be allowed entry into the country.
"Something needs to be organised to prevent this sort of confusion from arising again. Authorities in many locations appear totally unprepared for the volume of holidaymakers from the UK."
