Ah, that requires the specialized skill of deciphering Airline Hieroglyphics!

As so many websites are substituting symbols for plain, old English words, it becomes harder and harder for the newcomer to decipher what some of those symbols and apparently random numbers mean. To some folks, calculating the flight time by determining the difference between departure and arrival times makes perfect sense, omitting that little nuisance known as "time zones" - and seemingly random digits like 7:45 in an unlabeled column will mean nothing to them.
