Why do boarding gates close so early?

This is an effort to get passengers to the gate early enough that everyone has time to board and the flight will be on time. Aircraft are so busy now that it may be rare for boarding to start at that time, but having the passengers ready is an important step to getting the flight on its way.

If you missed your flight due to traffic, the airline may label you as a no show and cancel your entire itinerary. This is why it is important to call ahead and see if you can be rebooked on another flight so that you can still fly. Chances are, you will need to pay the rebooking fee.

Pressurization only works in an airtight fuselage. Were you to open a plane window, the compressed air inside would rapidly rush out, atmospheric conditions inside and outside the plane would equalize, and everybody would die.

MORE DETAILS

If the plane is somehow kept pressurized, the cabin pressure is usually equivalent of 6000–8000 ft, which is lower pressure than the outside at sea level. Which means as soon as you unlock the door, it will swing inwards with a lot of force, as air from outside rushes in to re-pressurize the cabin.

No emergency door can be accidentally opened by passengers. They are all automatically locked from the cockpit before you ever board, and in any case in flight they can't be opened due to the pressure differential inside and outside the plane.

How do flight crew normally open a cockpit door? Since the incidents in 911, pilots and flight attendants no longer have keys to open the cockpit door, which remains locked during flight. Access is granted via a keypad found outside the cockpit door.
