We are flying with bikes a couple times this summer and I’m wondering about current TSA and airline regs.

I looked at what is published and found that essentially all batteries must be in carry on luggage due to potential fire hazard. Definitely good to know with electronic shifting.

I looked for some information on CO2 cartridges and didn’t find anything.

Anyone know if they are allowed as checked baggage or carry on luggage?

And note that Delta made it a point to ask me about batteries when I checked a bag a couple of weeks ago. I had taken all my lights, my external battery, and my CatEye computer (Yep. I still use one.) and put them in a Crown Royal bag that came with a bottle I got for Christmas.

The only batteries I have in a checked bag are coin type batteries. And maybe AA or AAA NiMH batteries for my taillight flasher or camping headlamp. I do not have electronic shifting, so I am clueless on that topic.

Any form of compressed gasses have never been allowed on planes, that includes the CO2 cartridges. Get a good pump. Road Morph G or Lezyne Micro Floor Drive are my favorites.

A good luggage scale can pay for itself compared to a single over weight fee.

Recently some airlines have gotten more stringent on powerbanks, Southwest has some new rules on them. On some of the recent rule changes, they use the word charger when they are talking about powerbanks, so some of that may be ambiguous or confusing.

My rear light uses AAA regular batteries, My computer uses a coin battery. Don't know what the external battery is or what the headlight uses. threw everything in my carryons just ti be safe.

Thanks!

ooof. We are running 650b x 44mm tires. Well, a flat will get me a good upper body workout!

I have been pulled out of the lounge and escorted to the bowels of the airport as secondary screening found the Di2 batteries in my seat tube. Both myself and the bike just made the flight. It is a thing.

I wrote up a discussion of both the Road Morph G and the Lezyne pumps if you are interested, at:
Comparing Topeak Road Morph G and Lezyne Micro Floor Drive Pumps.

I have to totally deflate my tires for air travel to get everything to fit in the S&S case. Those tires are 26 X 2.25 (57mm wide), so I understand. It takes a long time to pump up both tires.

If you are bringing a solid bike case that has to get stored someplace, you might consider a full size floor pump for the initial pressurization. Then a smaller lighter pump in case you have a flat? For some reason, I assume that anyone that is using electronic shifting is using a solid hard case.
