So a low hour FO will be on Airbus or 737 for the first 5 years. Do most then apply for MH/LH, or do they stay SH?
The vast majority apply for the 747-400 at the first opportunity.
Most of the gripes on this thread seem to apply to SH. Do the same apply on the long fleets?
Sadly, yes. Except we only have to deal with them four or five times a month.
