So, we live in NI but have Irish passports. The plan is to fly to England at the end of June, so very possibly post-brexit. We can go via belfast or Derry but it's much cheaper with better flight times to fly out of Dublin.
Both dh and ds1's passports expire in July (ds's before we return home). I know you can travel domestically on an expired British passport, but not sure about Irish...
If we could get away with it, we wouldn't renew either. I've seen some stuff that implies minors can fly without Id for domestic flights at least.
DH considering passport card, but this is only for travel to EU, EEA or Switzerland.
Can anyone shed any light? This is our main holiday so if we can get away without renewing for another year (we normally go abroad) we will.
