Investment is a good thing. Sending planes from abroad to operate flights is not investment.
It's all well and good. You're clearly a aspiring EK pilot. What you need to remember is you won't start your career there. It'll be BA/FR/EZ then after several years if you're very lucky(!) you'll end up at EK. LHR is full for BA, LGW full for EZ. Where do you propose they go?
And take a look at the Middle East forum. Yes the uniform ad paint job at EK may look nice but the reality is it's a hell hole that most can't wait to leave.
When you've had enough of ULH sectors on minimum rest or you've had enough on Mid East night turns you'll want out. And when all of the local jobs in the UK here have gone what will you do? A 10 month contract in PMI for EZ or FR in Wroclaw?
It will be FR/BA/EZ you'll be desperate to come back to and will be begging them just so you can get home. Just a shame that their regional bases in the UK will be no more.
