I've been reading a great deal about "dress code" for Non-revenue passengers. Since I'll be a Non-revenue passenger (somewhat) but not an employee of the airline, am I also bound by the same dress code (like no jeans?) or is that specifically for employees (and not their families?)

From what I've seen so far it's been a requirement for anyone with a non-rev Boarding pass but I could be wrong....

I'd appreciate any clarification in this regard. Thanks!
