This . For short 03 hour intracontinental flights , regardless of whether I ' m in coach or business , I find I use mostly my iPad Pro . My 15 MBP is just too unwieldy in smaller spaces . Putting it out of the way for drinks andor food is kind of a pain , especially with a stranger next to you . Shorthaul business class is very similar for me . Last week I used my 15 MBP on a shorthaul 4 hour flight in business , but the seat next to me was empty , and I put my MBP on the traytable next to me and kind of sat sideways indian style , which was the only comfortable position I could find I ' m 5 ' 9 and 130 pounds , so it ' s not like I ' m taking up a lot of seat space . Even on longhaul business class flights 747777 A 380 type planes , I find my 15 MBP slightly unwieldy when dealing with fooddrink . For those times , I usually stick my MBP in the drawer on the floor , whereas I just tuck my iPad Pro next to me near the armrest . I was in a 747 in business two weeks ago , and I used my iPad Pro maybe 85 % of the time , and my MBP 15 %. Longhaul first is the only cabin that I find a 15 MBP is easy to use , both in terms of actual keyboard time , and also putting it out of the way , since I can just throw the MBP on the footrest and not have to contort myself putting it away . Was in a 747 in first last week , and I still found myself using my iPad a good portion of the time . If I could only bring one device with me , it ' d definitely be a 12 MacBook . Then again , I haven ' t seen the new MBPTB in 13 , which looks to be comparable to the Air , so that ' s maybe the best of both worlds .
