After seeing several posts mentioning FlightAware's flight tracking site, www.flightaware.com I visited the site to check our daughter's flight back to U of A, Tucson yesterday. Pretty cool I thought! Then I checked my local airport, Glacier Park International (KGPI) and got an error that the ID was not valid. Realizing that the identifier has recently changed, I tried the old ID, KFCA and saw only a couple flight ops for the the whole day. I thought that they needed to fix their database to handle the ID changeover so I clicked their support link and sent an email off reporting the issue. I returned back to the site about a few minutes later and discovered that KGPI was working just fine...thought I'd made a mistake by reporting the bug. Then I got an email a few seconds later from their support team reporting that they'd made the correction and apologized for any incovenience! Less than five minutes elapsed on the email time stamps! Pretty impressive
