Interesting thing happened today from ATL, on a trip to BWI. I gate checked my bag, and instead of getting a pink tag, I received a normal baggage claim tag (like if I was going to check it before I went through security). When I went to pick it up, the gentleman on the ramp said my bag would be in baggage claim. Sure enough, it came down on the turntable. This has never happened before. Just wondering if this is an anolomy, or if this is the norm, or if something was changing. It was a Delta flight, MD-88. Thanks.
