Not sure this is a hint, more a warning and how to get around it. I fly often and have to upgrade to Business so as to ensure a power socket at the seat. And I fly United because of their generous air miles packages which make upgrading affordable. However, United Business have new lie-flat seats, with a new 110V power supply instead of the old airplane-style one. The problem is that the socket is recessed in the console, and even the smaller power brick for the MacBook Air won't fit (you can insert the pins, but not far enough). There are a few ways around this:
- Upgrade to First -- the power socket is not recessed.
- Ask if you can charge the MacBook in First, and watch a movie at your regular Business seat while it charges.
- Bring an international travel adaptor with you (e.g. use the 3 pin UK plug on the power brick, and attach it to an adaptor for the US 2-pin style -- if your adaptor is a standard size, it's likely to fit into the recessed socket).
- Travel with the long power cord, and connect that to the brick and plug it into the recessed socket.
I have used both the second and third options above, which both work. Option two has the advantage of maintaining a healthier life-work balance, but it also relies on there being an empty seat in First.

robg adds: I don't travel often, but when I do, I bring the long power cord with me, just because the end plug is very standard, and will fit in any three-prong outlet, regardless of what might be surrounding it.]
