Has anyone here actually referred to a gate agent as a "GA" (jee-ay), a ticket agent as "TA" (tee-ay), or a flight attendant as "FA" (ef-ay) while talking in real life?

Do you guys really call the Admiral's Club as "AC" (ay-see)?


Just wondering because the other day, I saw a man who was pretty rough to a GA, who remarked "I am an 'ee-ex-pee,' and I deserve to get an upgrade." Found it very strange, but somewhat understandable if one lurks in this forum long enough
