Hi all,
I recollect that EK wanted to allow pax the use of their mobile phones in the air.

I was wondering if this has this already been introduced? If yes, what is the cabin ambience like?

I personally think that I would avoid longhauls with this. From my experience on trains:
Imagine paying thousands of bucks for an F-ticket just to suffer the self-important chatter (these are also usually very vocal calls) from fellow pax. I also think it would severely mar the premium experience and counteract the EK marketing message of "private" flying (e.g. suites).

Cheers
Hansie
