Unless you really enjoy the Citations and Embraer corporate world, airlines have a superior QOL than Netjets in terms of :
-Pay ( the gap is growing)
-Retirement (netjets has a good retirement, just not as good)
-Schedule (with average seniority I'll spend 7 nights out of my bed in Feb)
-Travel benefits (yes they do work in the airlines)
-Seniority progression
-Standardization (netjets is as standardized as they come in the biz jet world)
-Pre/post flight work
In today's world, the only advantage I see for Netjets is the home basing if you want to live anywhere other than an airline base.
Netjets is a very good company, but the seniority progression and schedule are two very big drawbacks IMO.
