About 2002 we had a pilot park a skanky old fifth wheel trailer in the back of the parking lot at the Airways building for several weeks.

Jack Lewis put out an email - whoever's trailer that is, get it out of there. And don't wear your uniform while you do it.....

I've been meaning to update this post in case it helps someone else. My family started fulltiming in August 2016, the week of my interview as it turned out. We roamed almost 2 months under the old company and then came to Memphis for indoc and training in the fall of 2016. Since training we've been all the way out to CA, all the way up the coast to WA, and back inland to Yellowstone, Mt Rushmore, Colorado and more. This year we're spending the winter in Orlando, which is not too bad.

Travel to/from work has been relatively easy. I self-identified during indoc, and both company and union reps told me to use business from wherever I am. Under the new j/s system it's mostly business anyway, but nobody has a problem with me jumping to work from a different place every month. In the rare places with little or no FX presence (RAP, for example), I've jumpseated on other carriers with very little trouble.

If anyone is interested in more details, I'm happy to give them. PM me here or find me on FB.

I personally haven't used "staging" for 20 years. It's a lower priority and can be bumped by anyone in the company using a business status.
If you are talking about jumpseating directly into a reserve assignment, then, no you are not protected. But, you aren't really legal to do that anyway, due to the 11:30 duty limitations for jumpseat protection. (The time from your jumpseat showtime until 30 minutes after your trip's final land time cannot exceed 11:30, in order to be protected if a company jumpseat fails to get you to your domicile). If you are assigned a multi-leg or international leg trip, you will almost certainly exceed that 11:30 time limit.
If you have an AM reserve assignment that commences at 0130 local time, you would need to jumpseat in on the previous day's AM inbound (0500-0900 local launch, with a 1000-1300 land time), to be legal if using a Fedex jumpseat.
Short answer - don't jumpseat using a Fedex jumpseat directly into a reserve assignment.

Coorection - it's 13:30, not 11:30 per CBA Ch. 26.J.2.a., and there must be at least 1:30 between the scheduled block-in of the jumpseat, and your show time in order to have the jumpseat protection. Sorry, should have looked it up and verified it before posting.
