Keeping current on one Boeing and two Airbus types would be manageable for cabin crew, especially for those already flying the A380 and B787.
Unfortunately the cabin crew are in the same position as most other CC at unionized legacy airlines when these airlines have to compete with low cost and Middle East airlines. Their terms and conditions stand out as being well ahead and are in the firing line when costs need to be cut. The baggage handlers got screwed over last year and it's time for management to move onto the next target.
Personally, I would be more flexible to maintain my income level especially given the current situation.
Realistically, the days of highly paid unionised cabin crew are numbered unless the traveling public is willing to pay higher fares. This is only likely on routes to North America where there is little competition and the US airlines are in the same position. Any route with a ME or Asian airline available will be tough.
