I was wondering, in BusinessElite, does anyone ever change into more comfortable clothing, like sweats or something simular for overseas flights to Europe? I have a flight from ATL-CPH this week, and thought it might be good to change into lightweight sweats and matching t-shirt. When I've flown to SYD and AKL past two years, I changed clothes after boarding which was quite comfortable during the long haul fights in lie flat seats in business on Air New Zealand and Qantas. So I am wondering the flight to CPH is long enough to "get comfortable," or if anyone else does this. Or, maybe I shouldn't be so self conscious since the Businesselite cabin for my flight doesn't seem too crowded.
