I just did a trip to South Africa with an 11x14 Phillips compact. I bought a Parker shipping case which accomodated the camera and 3 holders - that was one sub 50lb piece of checked baggage and I checked the tripod (a CF Gitzo), change tent and other bits and pieces in my other bag. No problems at all - in fact, it's really very little more effort than an 8x10. The camera weighs 16lbs (with a plexi GG which Bruce Wehman kindly made for me), the holders are around 3lbs each and Parker shipping cases are lighter than most. For lenses, I carry a Computar 240mm and a Cooke XVa - the latter with an extra front element: the lenses give me the following focal lengh combinations - 240mm, 311mm, 368mm, 476mm and 646mm - a great range for my needs and really light considering it all functions with only two shutters. I have a handful of 77mm filters and a couple of step up rings and a 77mm wide angle rubber hood. I actually chose 11x14 based on it's portability for travel. 7x17 is equally easy, but anything larger becomes a big headache for airline travel. It's all about planning and effort...
