I have had my bag which is one of those airline ones for 5 years now, had to have it fixed 1 time when Delta crushed it and they shelled out the $150 to fix it, but I also have the snap on bag that goes on the front, let me say this, when that bag was in the shop, I was able to make it 8 days on the road out of a little duffle bag, and I still do that, I have a change of undies, and socks and t-shirts, for every day, carry 1 pair of pants, and 2 work shirts, plus 1 polo shirt, and I also carry a pilot bag that has my manuals and paperwork and my IPAQ Pocket PC in there so that I don't have to carry a laptop anymore(does everything my laptop does). You guys that need a new change of clothes for each day are nuts, half the time you get in late to your destination and don't need to change anyway, if you got rid of all of that clothes and packed your bag like a man insted of a woman, you could make it in a small bag for 7 or 8 days, I find it much easier to get through security and much easier to pack, I do my laundry, add the socks, undies, and t-shirts and I am done, I just wear my polo shirt with my dress pants and keep everything simple, you guys that have 3 bags and complain that you can't make it for 7 or 8 days are idiots, what do you need? that you can't pack in 1 bag for a rotation, I guess us ex-military types know how to pack lite!!!
