Have any Irish passport holders had difficulty flying into the UK since the new ETA system came online?

[CurdinHenry]

Clearly there's no doubt Irish citizens are allowed in without one in recognition of the CTA but has anyone come across an international airline that didn't understand this and made boarding difficult?

No. Flown half a dozen times and you just go through the EU citizens bit and/ or use the auto gates for EU passports.
The only annoying bit is having to wait for friends/ colleagues who have U.K. passports. 2 of my colleagues missed our flight a few weeks back as they were in a massive queue

Also flown with 4 different airlines and zero issues with any.

No, the ETA is completely irrelevant to us.

It’s an EU passport so there’s no reason why anyone should make it difficult. No different to having a French or Spanish passport.

The airline aren’t the ones controlling the immigration anyway

No problems here. Often Irish flights go into the domestic UK terminals or gates so there is barely any checks anyway.

It is different because other EU nations aren't part of the common travel area. It is now a problem for dual nationals to enter Britain on their other country passport. Irish passports are still valid.

But to answer op question, a member of my family used their Irish passport at the weekend with no issues.

It's very different

They sort of are. Airline check for visas and entitlement.

Feetballislife an airline can refuse to let you travel if they think you don't have the right visa and such.

Tukatuka for the UK an Irish passport is very different. No visa waiver is needed, no permission is required. Such confidence in your own misinformation.

OP I've had no trouble, not even with Ryanair or Easyjet and they're usually the worst for not knowing the rules.

The rules have tightened up though for flights. You can't travel on your driving licence or expired passport anymore!

None
Ireland and UK have a long established common travel area.

Are they generally aware that dual British/Irish passport holders are exempt from the rule where you have to enter UK on your UK passport? My son is dual but only has an Irish passport at the moment.

No problem at all. Ferries are also no problem.

No that's the opposite direction

Yes they are in the first instance. If you can't satisfy them you can't board.

This is exactly what I'm worried about

Just got a bit of hassle from a non European airline

I might get him a British one, I can't be arsed arguing and it's the last time I'll have to do it (he's 13).

We'll be going to France from the UK and back, Ireland which I doubt will be a problem and possibly Norway.

I'd get both (if nothing else it's a spare if you lose one) but yeah it shouldn't really be an issue
