Hi Devin @Dev_Renae, in your three days since joining this forum, you have posted some interesting questions and generated worthwhile discussion - thank you and Welcome to TypeOneNation.
My response to your first two questions posted here is “Yes”; I use a G5 and have never used an OmniPod so I cant respond to your third question.
User manuals have specific “restrictions” for airport scanners, but generally avoid allowing pump and CGM scanners to go through x-ray; I have never had any problems with any of my pumps after wearing them through through “full body scanners” and with earlier pumps wearing them while going through the old style devices. You can find considerable coverage on this topic by using the “search” at upper right of this page; I suggest that the postings by @Joe, a very frequent international flyer, might be your best guide.
As far as hypo/hyper events while flying, I have had tendencies toward both but further analysis often revealed an underlying cause - such as not properly accounting for time changes and meal-time bolus. Your shot-hops probably would not cause this problem, but you might want to stay very aware of irregular eating times. On my pumps, now Tandem and formerly MiniMed, meal bolus ratios changed with specific “profile” so you should be aware of this and do not automatically accept the estimated bolus that your pump suggests.
Hope to find you soon as my flight attendant; is SRQ on your itinerary?
