Please be Seated—I’ve found that for long-haul flights, the aisle seat is the best seat for bathroom breaks, and a little more leg and elbow room on the aisle—watch out for the food and beverage carts. Similarly, bulkhead seating (the first row of seats) and the emergency-exit row offer a little more room. Some airlines offer coach seats with extra leg room at a price, e.g., United’s Economy Plus. To me, Economy Plus on an aisle or bulkhead is as good as Business Class. Also, take a jacket—in my experience plane cabins can be quite cold, no matter the destination or time of year!
