With Brexit looming I availed of my right to hold an Irish Passport.

Ireland also has a separate Passport Card which is credit card sized and valid for travel within the EU/EEA/CH. It’s easier to slip into the front of my man bag and I use it for most travel with BA in Europe.

But I also bring my UK passport and when I arrive at LHR or LCY I make a decision based on length of queue whether to use e-gates with the UK passport or the Irish Passport Card with an immigration officer.

I’ve never had a problem travelling on one (all duly entered on API with BA) and coming into U.K. with the other.
