Our packing list took into consideration the airline baggage limits. These will of course vary by airline and itinerary, but basically, for our plan, we identified these limits (per person):  One checked bag weighing not more than 50 lbs (or 23 kg), one additional bag (containing the bike) weighing not more than 50 lbs, one carry-on bag, and one personal item.
	  
	  Our touring bicycles, once packed in their travel bags, are very close to the 50-lb weight limit, and in fact, I could not include my pedals and some tools, or I would have exceeded the limit. These items had to be packed into my checked bag.
	  
	  The checked bag contained all the clothing and other items I needed for the several days of riding, as well as items which I could not put in the bike bag (e.g. pedals, fenders, bike rack, tools, bike shoes, panniers, handlebar bag and its contents. It also included a clean outfit to wear for travel home at the end of the trip.)
	  
	  My carry-on bag (a small backpack) included things that I wanted with me during the flight such as personal items, an iPad, neck pillow, noise-canceling headphones, identification, money, travel documents.
	  
	  Finally, the "personal item" was a sport sack in which I packed my bicycle helmet, gloves, bicycle glasses and a few other items. The helmet could have been packed in the checked bag, but I was concerned that this bag might be too full and/or the helmet could get damaged if the bag was stacked or dropped.

Some of these items stayed with our bike bags and suitcase (stored at our starting hotel), but most of them were packed in the panniers and carried throughout the trip. This sorting out was critical so that we had the necessary items with us but left behind the ones we did not need again until the end of the trip, i.e., we did not want to end up carrying something like a neck pillow or a pedal wrench with us for 14 days!
