That's bizarre airbrake. I have friends in both camps and generally those on the LH fleets in BA are earning the same or more as EZY Captains. Are you sure you got your sums right? These guys are not particularly senior either.
Other issues highlighted were the requirement in future to take commands abroad in EZY on local contracts and the bosses unstoppable desire to turn it into orange Ryanair. With demand now exceeding supply for EZY commands I suspect the contracts may take another battering.
