I need to buy a smaller bag.
I learned this checking in at O'Hare a few minutes ago. It turns out, American Airlines has a 32-kilo limit on each checked bag. However, if your bag wieghs more than 22.7 kg, they charge you $50 for the overweight.
My bag weighed 33 kg until I removed my one-kilo Financial Accounting binder—just the binder, not the textbook, workbook, or CD—and rearranged my other two bags to distribute the weight better. The final score: Checked bag, 31.7 kg on the nose; carry-on bag, 7.7 kg; backpack, 8 kg; doctor visit co-pay, $10.
So, once I get to London and, a few hours later, recover from schlepping 48 kg of baggage up the steps of the Tower Hill Tube stop, I may pop 'round to Oxford Street and get a new bag. Because, see, the bag I have at home that would have perfectly fit the bill is inconveniently still at home.
Another thing: when did American start putting winglets on Boeing 767s? Look:
Quick follow-up to people who aren't pilots: This week's "Ask the Pilot" has an explanation of winglets. He also has a description of Princess Juliana Airport as well, which is the reason I visited Sint Maarten last winter.
