RVR800 - I'm getting rather worried as you're supposed to be the PPRuNe "glass is half full" optimist!
I think that the niche regionals and the low cost operators will do well; and indeed go from strength to strength. Carriers with high costs will go under - so everyone needs to cut their costs (and - most importantly - keep them low). I suspect that this current crisis will result in the survivors being unrecognisable at the end of the process - but at the same time, will be in a much stronger position to deal with competitive threats from around the world - and especially across the Atlantic - than they are now.
Beware of the light at the end of the tunnel being an oncoming train!
