The Owner greeting can quite often be the most confusing part of the entire trip. There have been times (like at the Daytona 500 or Super Bowl) where there was NO way to positively identify the Owner(s).
We do the best we can to be both in the plane and in the FBO while doing everything we do to preflight an airplane a prep for a flight (with no F/A for most of us). There are man, many steps.
Sometimes an Owner arrives early. Many times there is a slide in the departure time of up to 2 hours.
There are far too many variables in the mix for someone not flying the flight (NJA or otherwise) to judge what or how an Owner greeting should or should not have occurred.
What if the NetJets pilot originally referred to in this thread wasn't even the one flying this trip. There are 2,800 of us...
Bottom line, we do more than a good job for our clients. We do a great job. We hear it from them all the time verbally and through surveys.
Thanks for being concerned about us though.
