The rest facilities for pilots on EK777s are sub-standard, disrespectful and quite frankly are a '**** you' to the pilots from the company.
Having said that whining on prune about it is unlikely to get any results (irrespective of whether management actually read these threads or not). In the absence of any representative group to make a collective approach to the company it is up to the individual to write and/or speak with management to voice your concerns.
Ultimately if you are one of those who cannot get rest it becomes a matter of flight safety.
As a minimum we should have 2 business class seats blocked for our use on ULR flights.
