… Ah. So I just looked it up; no-one flies to Dublin from there (Aer Lingus is 2A, Air France is 2F). Possibly it’s a Schengen-only terminal.
(Living inside Europe but outside Schengen tends to get you the worst terminals/sections of terminals. Berlin Tegel used to have a tiny little terminal that, as far as I could see, only flew to Ireland and Turkey (not sure where the UK flights went from). Absolutely horrendous; there’d sometimes only be one passport control line, so if the person in front of you had an issue you might be waiting for an hour.)
