Go Around Flaps,
You've only missed one thing.
That is that there are many Command ready F/O's on Euro contracts that don't wish to leave their Families for a LGW Command. Their choice I know.
After UK tax and living/commuting expenses they will earn not much more money for a lot more responsibility c/w euro F/O conditions.
So easy will address the Command shortfall by small number of DEC's.
It's not helped by the appalling contracts on offer in AMS. This base might have created movement from some French/Italian bases but very few takers.
As the CEO recently said when questioned about the AMS contract "You don't have to take it ....somebody else will"
Wishing a happy outcome for Monarch crews.
