Wrong. Some carriers indeed require you to list on myidtraval or id90travel for the jumpseat (as Lakeaffect already pointed out). ALPA's jumpseatinfo.org page is a great resource to figure out what a given carrier requires for JS'ing.

Wrong. You cannot sit in the cockpit unless on your own metal (do I have to call it "the actual"?); subject to any limits imposed by the same interline agreements that authorize the JS in the first place, you most certainly can JS internationally.

As an aside, wasn't United running an experiment a year or so ago, considering opening up the flight deck ("the actual" ) internationally to OAL pilots? Whatever happened with that?


To shorten the answer a bit: you can JS on any carrier with a reciprocal arrangement with your own company (probably any US Pt 121 & a handful of Pt 135), subject to their rules & any rules imposed by that reciprocal arrangement. You can only non-rev* on your own company and/or their regional/mainline partners (subject, once again, to company rules on the subject). At many carriers (mostly on one's own metal), you can get preferential treatment on the JS vs NR (the ability to reserve the JS, for example), but that's company-specific. Probably the biggest single difference is, a JS'er can sit in the cockpit if there are no seats in back; a NR'er cannot sit in the cockpit. If you're listed as NR and think you have a seat, but at the last minute the seats fill... well, good luck getting the gate agent to re-list you as JS at push time....


*As Turbosina mentioned, you can "sort-of" NR on other metal via ZED fares/ID90. You pay for these--typically less than an online ticket, but not by a whole lot unless you're looking international--but still fly standby, usually at the bottom of the list (roughly equal to buddy passes).
