We’ve just been to Spain.
Me and husband fully vaccinated - no test needed to fly out or whilst there - we had to fill out a passenger locator form before flying and also take our vaccine information with us - mine was checked on arrival but DH’s wasn’t. DD did not need to test or have vaccine info as she’s under 12. DD did need her own passenger locator form.
We did not need to test whilst there - that’s been scrapped now for fully vaccinated.
We did need to book Day 2 tests for our return. We ordered them before we left so that we had a reference number - these reference numbers were required for the passenger locator forms that we had to fill in before returning to the UK. These forms were not checked at all on return to the UK but the airline check in staff did give them a quick glance before we took off. I’m sure this varies!
For travel TO Spain:
If you’re fully vaccinated you don’t need any further pcr tests, just your vaccine pass and their version of the passenger locator form.
If your children are under 12 they don’t need any pcr test or vaccine certificate. They’ll need their own passenger locator forms still.
If your child hasn’t had any dose of the vaccine and is over 12 then yes they will need additional PCR tests.
If your child has had one dose of the vaccine - unclear. The UK and Spanish gov sites both say that you must show proof of vaccination with either both doses of a 2 dose vaccine or 1 dose of a single dose vaccine. As children of this age are ONLY being offered a single dose, I would think that would be sufficient - however I’d check this, your travel agent or airline might be a good place to start?
For return to the UK:
For return to the UK
You don’t need a pre departure pcr test if file vaccinated.
Your under 18 children do not need a pre-departure test whether vaccinated or not.
Fully vaccinated adults and anyone under 18 do not need to quarantine on arrival back in UK.
Adults and anyone over 5 will need the day 2 PCR tests on return - book these before you go (we used randox and they were posted to us ready to use when you arrive back) so that you have the reference numbers. These reference numbers are needed for the UK passenger locator forms which you need to fill in from 48 hours before you return to the uk.
If you’re returning to the Uk AFTER the 24th October you don’t need to do the more expensive PCR tests and can do what’s called lateral flow or antigen tests instead - although I’m not sure if that’s been made official yet.
