Hi there!

I recently booked an award ticket on business class from BOS>DUB. I'm then flying EI economy to BIO. For return trip back to the US, I'm flying from LIS EI economy to DUB first. A couple of questions:

1. Will EI let me check my luggage through to BIO? Given that I'll be checking two luggages through?
2. For my return trip to the US, even though I'm on economy to get to DUB, will EI allow me to check two luggage? Or will I have to pay?

Any thoughts would be much appreciated!!

Thanks!
