momo, you'll find that a fair few of the 'popular' EK instagrammers are on the company payroll- if not actually being paid, getting perks in return for posting about how amazing it is.
I would take it with a pinch of salt. One of the more... how shall I put this... 'selfie obssessed' CC instagrammers who regularly says how amazing the EK life is, actually couldn't wait to leave the job after 6 months and was banging on about how much they hated the pax and the job was beneath them... until said crew realised that posting about how glam their life at the airline was would start netting them promo flights, press freebies and expensive gifts from 'admirers'... the account is now little more than blatant cross promotion and photos that would get anyone else posting them fired.
EK has a stable of CC and FC 'grammers who basically get free reign to post whatever so long as it portrays the company and the job in a positive light (while not being able to post about anything negative) It's all part of the promo machine
