Got to disagree with bmibaby.com.....
I would hate to see baby join up with VEX. In my experience of both, baby wins hands down. I don't think VEX actually is regarded as "one of the more professional low costs"; VEX seems to be trying just to be cheap - a sort of Belgian Ryanair, without the lousy customer service.... baby seem to be aiming higher than that.
It makes more sense for mainline to become a Virgin brand. Call them Virgin X, where I don't know what X is, but certainly not Express, Atlantic or baby!
Let baby rename - can't see them being bmibaby without bmi.... let them stand alone, and carry on doing what they do best. They are doing a great job of growing by staying away from the competition, providing a fine service to underserved parts of the country, and by not getting involved in the Ryanair v easyJet mud-slinging (both of these may do better to concentrate on the "my yields better than yours" debate, rather than who has the lower fares, imho....)
Viva baby libre!!
