US/EU via Ireland passport holder traveling to UK
I hold both passports referenced above and live in the US. I will be traveling to the UK via Delta. The Delta app is telling me to apply for the ETA but my Irish citizenship should make that irrelevant. Do I just show up at the US airport and show my Irish passport to an agent? Or is it easier to just pay the fee for ETA? Delta does not allow me to have two passports on file so they have no awareness of my Irish passport.
