Fence only 3-5 years? "Mergers such as NWA/REP resulted in 20 year fences as the REP pilots had no career expectations to ever fly a widebody aircraft." I'd expect the same goes for many who chose Hawaiian specifically to fly widebodies for their career and those who were happy to work for an airline that had zero widebody aircraft.
With the 330s being replaced and 787s delivered mostly post merger there is a lot to be lost in terms of widebody positions for Hawaiian pilots. I don't know how that career expectation can be maintained.
