I tell guys a senior FedEx trip is way, way better than most pax trips. A bad trip at FedEx is usually much, much worse.

The top 20% in most FO seats could hold the left seat of the same jet, but people camp here and get uber senior to avoid the pain and enjoy the better trips domestically.

Internationally, the trips aren't "that" different, although some are better than others. In my domicile the difference in good and bad are often in the eye of the beholder, and thus I often get once of top choices even though I bid 75% or so.

Again--for those lucky enough to get a call--look at bidpacks, and go jumpseat. You'll learn much, much more that way than rummaging through opinions on the internet.
