That is a very good question. The reason why water boils under 100 degrees Centigrade or 100 degrees Celsius is because commercial airplanes are not pressurized to air pressure at sea level, but to about 8,000 feet or about 2,400 meters. At this effective altitude, water boils around 91.6 degrees Centigrade. As an interesting fact, one of the reasons Boeing advertises flying on the 787 Dreamliner is because it will be pressurized to about 6,000 feet or about 1,800 meters. At that effective altitude, water will boil at around 93.6 degrees Centigrade.
