If your husband had booked these days as annual leave and had that request authorised prior to booking the holiday then you might have some come back against his company or be able to clain agains yout insurance but I've just had something similar arise at my work and the employee has lost her holiday deposit.
In this instance, she found a good bargain on the Net, checked her diary, thought that the dates were suitable and that she had no definite work commitments and booked the holiday prior to getting the leave formally authorised. However, she did have commitments that she had forgotten to put in her diary, colleagues refused to swap work duties with ther to cover (she's done this before!) and her line manager as result refused to authorise the leave retrospectively. She feels hard done by but her line manager and our employer are within their rights. And in this instance, because she hadn't got the leave authorised before booking the holiday, her insurers won't pay out on the grounds that this is her own fault for not ensuring that she would be able to take the leave before commiting herself to the holiday. She's got no other option other than to either forfeit the deposit or try and persuade the TO to change the holiday for her on payment of an admin fee.
Whatever happens with flyblue's husband's employer Olympic are entitled to the full deposit and whether they have any comeback with his employer will really depend on whether this holiday was booked because he assumed he wouldn't have to go on this business trip but hadn't yet booked the leave or whether he had already had the leave authorised, then booked the holiday and his employers are wanting to withdraw their permission for him to take leave on these dates.
