After submerging in the Atlantic, the captain said the airplane is "Pressurized". While some might think otherwise, it is possible for a submerged plane could retain air for a period of time. It should be noted that when at altitude, a pressurized airliner maintains internal air pressure that is considerably higher than the outside air. When underwater, the situation is reversed. Because of this, even a perfectly intact airliner would certainly have leaks. As the plane in this situation is only perhaps 100 feet below the surface, the water pressure is 44 pounds per square inch. At cruising altitude the internal pressure is maintained at about 12 pounds per square inch, with is equal to an altitude of 6,000 feet.
