If you've been following the news - almost everyday there is some sort of incident that has to do with airline security, evacuations, bomb threats and so on. Baggage screeners can't possible scan every bag due to time restrictions and the sheer amount of travellers.. especially during holiday season. I do believe that airlines are still very vulnerable to explosive materials kept in checked baggages (if not detected obviously) Just a thought.. but.. why not have a separate plane to carry all checked baggage? Lets say you're flying from LAX to JFK on American Airlines. When you check in at the counter, your baggage is bundled with baggage of other passengers flying the to JFK.. on other airlines (like united, continental, etc) I mean, I am sure at 7.20 am there are a bunch of flights leaving from LAX to JFK at the same time. So have a plane carry all the baggages of all these passengers to JFK. One plane can easily carry baggage for about 8-20 flights (I'm assuming) so talk about the financial impacts wouldn't arise. Additionally, since the flights with passengers would weigh much, much less due to no checked bags.. they could have less fuel, and save more money. All the checked baggage would obviously be tagged with the appropriate information as to what airport they are supposed to go to.. and thats being done now anyway. Basically, just fly with your carry on.. and pick up your checked baggage that comes on a separate plane at your destination. No stress for passengers and security personnel either. What do you think?
