I'm going for a week on a package tour later this winter from Canada to the Dominican Rep., with Sunwing Airlines, who are apparently very strict about size and weight for carry-ons. I want to take my D500, 300 f4-pf and 1.4x TC, as although it's not a birding trip, I'm sure there will be some there to photograph. That gear + even a light pack will exceed the allowed carry on weight and probably size, and I'm loath to have it in my checked baggage in case it gets lost. Has anyone successfully got through security and check-in with similar gear in a similar situation by wearing the gear with a BlackRapid strap over the shoulder, or does anyone have any other suggestion? Thanks in advance.
