Flying out of Limerick

Greetings from Ireland, personally I'd arrive one hour before for a flight from Shannon to the UK. But the airport generally recommends 2 hours before, just to be sure to be sure (and to give you more time in their duty-free shops!)

ps so just in case, best to arrive 2 hours before

Thanks Stephen!
