Bit of a thread revival but I use a Studio Ocean Mark reel bag - it can take all my reels, a 15" laptop, Go Pro and associated kit, phone/wallet/passport/Kindle/Ipod, etc. A nice bit of kit that I use as my carry on bag along with an HPA roll. Spools, multipliers with non removable spools, jigs, accessories, etc., go in the Loomis roller bag in check in along with the tube with my rods and clothing in.
