Theoretically yes, limits for alcohol and tobacco could be the same as they are now when entering UK from a non-EU country,  but stuff bought at the airport by UK-bound travellers could be tax free.  I wouldn't base holiday plans on that premise.

We shall see.

Departure for UK bound travellers is already set up for the special pre flight identity checks needed to enter the country. Likewise waiting to show passports on arrival, which those coming from Schengen countries do not.

The only likely change at either end is if customs import limits and inspections are re-introduced. Those of a certain age will remember when you could only take back 200 fags and the red and green channels. Nothing to declare, sir?

Family members left this morning and told me they had to go through duty free first. 

Passport Control is after duty free where you go to the gates. 

UK will also need a large number of new low paid workers once the blue channel at the airports is gone.

It could also fall into the category of bureaucracy, seems a bit of that in Portugal, keeps a few jobsworths in employment and the unemployment figures down. Of course it’s none essential, hence sometimes there’s no one there, but when they do turn up, they can draw a wage.

"Why the check leaving Portugal?"

The data is probably transmitted to UK Border Force so they know who's coming and can be waiting for you at the other end. Seems a bit of overkill since airlines are required to send API to officialdom.

Possibly also a way to determine if anyone's overstayed their welcome. A bit strange also, since anyone driving to and from Portugal, or travelling by train or coach,  is not subject to the same checks. Evil do-ers obviously travel only by air.
