iflyguy,
I've had this conversation with a few 320s FO's ..... as you rightly pointed out there is no right and wrong- at the end of the day you'll decide what suits you.
I'm kinda in the same position as you, same age group 320 FO flying in India (but not near command). I took the EK offer and am heading off in a few months. Had command been offered to me (or even if i was a Captain) I would still take the EK offer. But hey that's just me.
IMHO there are a few reasons to not take the EK offer. 1) Family obligations 2) Monetarily and 3) If you're not gonna like DXB.
Reasons for.
1) Professional growth. I know PIC time is gold but ... at 27!! If I stayed in India command would come (eventually) ... then what? Fly mainly domestic on the same aircraft in the same company with the same flying culture? No thanks!
Id rather work abroad and gain a new perspective. In the long run it'll make you a better pilot no question about it.
2) Iv heard a few people say "once you taste the left seat its hard to go back to the right seat' ....
at 27??? Maybe if you were in your 40s then staying as an F/O becomes more complicated but we have almost 40 years of flying ahead of us. Captaincy will come, quite frankly flying in one country or company your whole life- you'll have blinders on.
Career growth career growth career growth. I know a lot of people on this forum will ridicule us for wanting to move to EK (we know it has its negatives) but we all have our comparisons. Indigo is stable and growing- but remember the industry in India will be thrice as big a decade from now- moving back will be an option and you'll probably be able to move back as a captain should you want to 10 years from now.
My 2 cents
