Polyamory/ENM and Flight Attendants/Crew

My partner (40M) is a commercial pilot and I (32F) am a commercial flight attendant (different major airlines).We have been ethically non-mongamous/polyamorous for our whole relationship (1.5 years). I often am asked why more pilots and flight attendants aren't ENM/polyamorous. Non-airline people always assume there are lots of us. I also find it strange considering our professions fit so well with non-monogamy. Anyone else here part of the ENM/poly community?
