The subject is (very heatedly.....) debated right now.
In a nutshell: All 4 KLM ERF aircraft are currently operated by Martinair; two as dry-lease and two as wet-lease. Martinair`s 767`s will be phased out by the end of next year, maybe even sooner.
The Martinair pilots will probably end up flying the remaining 7 MD-11`s and 4 ERF aircraft, with perhaps some junior pilots moving over to KLM. How the KLM pilots will be compensated for the loss of 4 of the top paying aircraft to the cheaper sister is being debated as we speak.....
In this scenario the job losses at the cheaper sister are being transfered to mainline. Not a good strategy for advancing your T&C`s as a pilot group, so care is needed.
The Martinair (767-)cabin crew will all be moving over to KLM, but how and where is also still being debated.....
