I’ve only ever flown with a bikes running tubes so never had this problem. A mini pump is enough to get me riding on my road bike. Looking at gravel trips. Unlike my mtb, I’ve never got my gravel tyres seated without a little help.
If you travel with tubeless what kit can you take on the plane? CO2 is generally not allowed. Are Airshot canisters? They aren’t that much different to Sigg bottles. It would be useful to have something that could reseat a tyre should I need to. It occasionally happens and would be a faff without the right stuff.
Will probably try and buy some CO2 once we arrive which would then let me use my race setup. CO2 and sealant not ideal but it would be ok for a week.
