How many more rolls of the dice for most of those?
"Regional Airline Group" sounds rather grandiose...The impression with Stobart Air is that it is a fire sale/required sale for the Stobart Group to relieve itself of debt that has accrued with it`s miscalculations in the Airport & Airline divisions over the period.
A deal would be dependent on Stobart Air retaining the EIN franchise of course & perhaps IAG/EIN will push for an even tougher deal themselves now.
