After using BA or American to fly home from Chicago many times, I have now started using Aer Lingus (last 2 flights)
newer equipment and i fly into BHX through Dublin for same price or cheaper
AA still using old 767s - 1 tv every 10 rows and headphones dont work properly
BA 777 was decent but landing at BHX makes Aer Lingus worth it for me
In states Southwest are probably my fave cheap airline !
