How many bikes can I fly with?

I'm curious, could you please elaborate on the specifics of your question regarding flying with bikes? Are you inquiring about the number of bicycles allowed on a particular airline, or are you asking about the technical feasibility of transporting bikes by air? If it's the former, it's important to check with individual airlines as their policies on carry-on and checked baggage, including bicycles, can vary greatly. On the other hand, if you're exploring the latter, it's worth noting that while it's possible to fly with bikes, there are certain preparations and considerations that need to be made, such as properly packaging and securing the bicycle to ensure it arrives safely at its destination. Could you please provide some more context or clarification on your question?
