There has been a request from the upper floors to put a business plan together for such a deal. The money saved would be a boost for the bean counters. You forgot to mention NO school fees in addition. Taxes? You would be paying them anyway if you were based back home. It is not overseas basing, but rather a commuting contract. Much like KAL, Turkish and others. How many experienced captains has EK lost to KAL recently and to other carriers that are in one's home country. More importantly, the wives become happy again raising kids in their own environment/culture.
But only if this is approved, or something like it, by those in rarified air.
