I just got an email, nominally from Southwest Airlines, advising me of my upcoming itinerary:
Depart SAN LEONARD CITY IL (SLC) at 6:30 PM on Southwest Airlines
Arrive in PHOENIX CA (PHX) at 2:19 PM
So apparently SLC is not Salt Lake City but a nonexistent city in Illinois, Phoenix is in California now, and flying between them takes negative 2 hours and 11 minutes (even after accounting for time zones).
Yep, seems legit!
