That’s why I’d be surprised if there were widespread offers of VR to A380 crew.
The EA allows the company to tailor their VR offer to individual crew members. One pilot may be offered something different to someone else depending on their specific circumstances.
The 747 crew you’re least likely to get a return from if they do a conversion course post March next year are those who turn 65 in the 18 months after that time. These are the ones most likely to get a targeted VR. There are less of them than you’d think.
Id leave those 747 crew out of it completely and assume they'd either give up, call it a day early or hit 65 before they can be trained.
