American Airlines and Air Canada are reportedly in talks with the Transportation Security Administration for a trial program in Boston likely later this year to let travelers tag their own checked bags for the first time in the U.S., says an ABC News report. Delta Air Lines says it's in talks with TSA for a trial at another airport. It's designed as a service to help speed customers through check-in. 
While self-tagging -- or letting travelers print and affix destination tags on bags -- is common at foreign airports, only airline agents can currently do that in the U.S.
