However if SWA requires a login with a RR number, similar to AA requiring your AAdvantage number, that can absolutely be sorted. You could use a VPN but it's trivial to sort by flight who used that login on what flight and by process of elimination, one person will be left after doing it over say a dozen flights.

Will anything come of it? Absolutely not unless there is an incident, you hit something on the ground after landing, who cares, your device will be looked at and records will be pulled. This has happened to 121 crews in the past and licenses were suspended for weeks/months because of it. Worst case you get fired like the AA F/O in JFK.

Fo the CA's who are playing dumb, just an FYI but I personally spoke to another CA whose FO posted an inflight pic on FB, took it down within 30 minutes, and the FAA still found it. FAA came after the CA, luckily nothing ended up happening but it caused a lot of heartache.
