As CCM said,
I was going to suggest you look into going '50% or 75%' part time. I used to work as cabin crew for Britannia based at Manchester (am training to become a pilot now) and i know that they had this sort of part time scheme. However i think it was only offered to people who had been there a while (but you never know until you try!).
If you have quite a bit of experience in the job and the airline you apply to is in need of CC then you do have some bargaining power to get a permanent part time contract.
As i have been told many a time...'if you don't ask you wont get'.
Good luck with things,
Dave
