I have done loads of reading about this, I swore to myself I wouldn't need to start a thread to ask advice, but I'm just very confused.
I keep seeing the quote 'make sure your passport is less than 10 years old'. Now I understand about the extra time over 10 years not being valid anymore, but are they saying that if your passport ever had extra time on it, the whole passport is no longer valid?
This is what Jet2's website says and helpfully (or not) to emphasise the point they use a passport that is exactly 10 years old.
"Your passport’s validity: EU countries now require UK passports to be less than ten years old and still be valid for at least three months at the time you're due to leave an EU country."
My passport doesn't expire until August 2028 but It was 10 years and 3 months old at the time of issue. Is that a problem? My head hurts.
