Just the facts about money etc..
Base is Ok taking into account dollar plunge isnt an issue for latin americans.
Housing, you will be offered a 3 bedroom apartment in a decent compound (decent NOT great), if you try to get your own place money is not enough.
Transportation, if you leave in that compound they offer you and have kids you definetly need 2 cars so is not enough to pay the monthly payment of 2 average cars (dont do the classic mistake and go for the Land Rovers, BMW etc.).
School is enough for an average school, that is if you can find one, I think school is a really tough subject in the Gulf (not only Doha).Couple of guys left QR because they could not get a school for their kids, or go find a !!!!ty one.
Exotic destinations mmmmmmm, not on 320 dont think India is as you see it on Travel Channel.
Well just a little info, my advice there is a more mature carrier very close from Doha, because if you think a lot of 320 time will put you closer to a left seat that is absolutely false. Command time is easy 5 years nowadays.
Ok remember as they say in your country, "prometer hasta meter, una vez metido al chin...... lo prometido"
Ups i almost forgot you will NEVER fly 80 hrs on 320 maybe 60 if lucky.
