The post has annoying little errors that make it harder to read. The figure says BA286, and the text says "BA287 means British Airways flight 287". So does that mean you always add 1 to the flight number shown on the screen, to get the actual flight number? "388 equipment type: 389 refers to Airbus A380-800". Again, you add 1 to the number shown on the screen? Why does "389" mean "A380-800" and not "A380-900"? I realize it's possible to figure out that these are just typos and you don't really mean "take the number shown on the screen and add 1 to it to get the actual flight number", but why would you make your readers deal with that kind of confusion?
