With some trepidation I have included 2 EI flights on my reissued AONEWC intinerary.

I am steeling myself for all its LCC ways - which grow more alarming as I delve deeper - but am particularly concerned about the luggage allowance.
Will I have to pay the EUR5 for every checked bag? And am I really restricted to 20kg as per their website and my (now paper) ticket? Or does the highest baggage allowance apply since it is part of a single first class ticket?
Apart from that, how scared should I be? I can live with buying my lunch and drinks and will almost certainly survive the short flight from BHX. But how bearable will 3 hours plus be for the DUB/DBV segment? I am not very experienced at Y travel any more and fear I may have become too soft to deal with such a hard-core economy product as EI offers.
