A German Pilot Union will quite rightly have the interests of their own members far above the interests of pilots that work for a Middle Eastern airline that is viewed as a strong competitor.
Vereinigung Cockpit have been staunchly opposed to the new 'lower cost' longhaul operation that Lufthansa has launched with A340s to destinations such as MRU, MLE, MAA and funnily enough soon to PTY as well. Such routes were deemed to be not traditionally feasible and required a lower cost base, yet Emirates has been operating successfully to MRU,MLR and MAA for years. Lufthansa will be codesharing to and from PTY with Copa, just as Emirates will be doing.
I would love to be proved wrong but if Vereinigung Cockpit is offering an open ear to the complaints of EK pilots, I feel it is being done not with our interests at heart.
