When I did the CF, I planned to spend a few days in Madrid post-Camino, so I stuffed both my pack and an extra set of clothes into a duffle bag. When I arrived at Lavacolla, I just took out my loaded pack. The duffle with my extra clothes I forwarded to the hotel, which was kind enough to keep it for me until they saw me six days later, trailing Camino dust into their clean lobby
Not bad for a cheap bazaar purchase (for marktqm, read: "tiangge")...
i took mine on as a carry on, and no one seemed to be concerned about straps hanging out. may be a different story if you are checking it. so much easier taking it with you, no chance of lost luggage.
my flight arrived in vancouver at 2pm and i was on a city bus at 2:25pm. now how is that for timing. no one going thru immigration,
I took a 70L Osprey pack and had to check it. Let me say that it was way to big but I thought I knew it all back then and learned the hard way. Back to question - I bought an airport stroller bag on Amazon for about $13.00 and it worked great.
I don't even tie off the straps now. I turn up with my poles on the outside of the bag and ask the clerk if they want the poles on or separated from the bag. Either way they have all come out fine. I don't like doing hand luggage only, I like to keep my big suncream, nail scissors and whatnots.
