Flag Pole to go seems to be what I see most. I think all flagpoles have got to be wider than the 1” diameter in the guidelines. Technically they’re supposed to be shorter than 10’ too, right? Just keep it collapsed upon entry and maybe have someone with a less complicated security walkthrough situation (such as having no bags. I bring a hydration pack through too so I gotta free up my hands to open it up).

I’ve only used the flagpole maybe twice before deciding a full on flagpole wasn’t for me. Though I found this harness to be helpful in allowing one handed use and waving of the flagpole. Super helpful. And I was able to wave the flag vigorously one handed with this. But the stitching kind of roughed up the stomach area on my sweater where the flagpole rests against your body.

One thing I’d note as well is that your flagpole/flag can get lost in a sea of them and you’re far or the lights aren’t hitting right or there’s no wind and you aren’t able/in the mood to wave the pole in a figure 8 so I thought it was a cool idea to vary flag shape or even add lights to your pole (though in a way that won’t get in the way of you retracting and extending the pole when you inevitably have to cross into low overhead clearance areas or for wind).
