Omnipod for the win. But, yeah, I have a bunch of disposable needles in my kit as a backup.

Even so, travel is stressful. My carry on is full of backup pods/sensors. But now that my insurance is being annoying and only filling a month at a time, I don't always have an extra...

I'm fortunate to have the income to support buying backups when I had insurance issues. During the Dexcom G6/G7 switchover and the switch to the Omnipod, I had just filled a bunch of G7s but the Omnipod didn't support it yet, so I ended up having to buy G6s out of pocket. Even with coupons from the manufacturer, it was still costing me $200/month.
