The only thing is, when this was proposed on the VPF forum with a poll, it was a resounding NO vote to help out by the VA narrow body pilots. They feel they are immune to any reductions in fleet or flying. Maybe when it gets a bit closer to affecting them they will reconsider.
Except that it can never be reciprocated as there just aren't enough WB pilots to subsidise the 737s if the situation was reversed and the 737 was in trouble.
Those who went onto the widebody went in with the full knowledge that it may not work. Some people didn't take it because they didn't want to take the risk. You can't take the risk then expect a bailout because the cards haven't fallen your way.
Nothing against the sentiment except that it just doesn't work in reality and the pay differential between the two is significant.
