Ever since I first heard about a man using his BlackBerry to check into a flight - he was running late and didn't have his boarding pass - I've been wondering if this was just a one-off instance, or if it was going to become a growing trend. According to RCR News, Delta Air Lines is now allowing passengers at LaGuardia Airport in NY to use their cell phone as a boarding pass. Domestic customers can now download their boarding passes to their phones via Delta's website and go directly through security rather than visiting check in (if you don't have bags to check). OK, I seriously wish I had an excuse to fly out of NY using this new handy dandy service. Let's just hope other airlines follow suit!
