one of my pet peeves - the myth that a bp/w does not travel well. i travel with my SS bp all over the place.
1. it packs very small. the bp goes in the bottom of your carry-on and takes up no room. the wing rolls or folds to almost nothing. all told, it takes up less room than a standard BC.
2. the weight argument makes little sense. just do the numbers: a standard SS bp weighs 5-6lbs. add the d-rings and the wing. plenty of "standard" BCs weigh in at 7+ lbs. there are a few travel BCs that come with compromises and weigh less than 5lbs (excl. weight pockets). so the difference in weight between a standard BC and a bp/w setup is insignificant and in many cases the SS bp/w is actually lighter. not to mention that if you pack it into your carry-on, weight does not even matter because they do not weigh your carry-on except for a few flights to very exotic destinations on island hopper planes. in those cases you theoretically may have to pay for an extra 3-4lbs over the weight of the very lightest travel BCs. That's a very minor charge. it becomes outright ridiculous when put in perspective to the cost of a trip to such an exotic island locale.
