When you compare the zone design of Classic and TBC, you'll quickly notice that Classic rarely has any hills / mountains to climb that aren't easily accessible in the middle of a zone, neither does it have deep gorges like in Nagrand, which are a big pain to get out of without flying.
The TBC zones, at least geographically, are very much designed around flying, that's why you have a zone such as Blade edge's with its multiple plateaus, Nagrand with its Gorges and huge Lakes, Netherstorm with its multiple "islands", etc..
Sure, you can traverse them without flying, but one can't deny the massive advantage flying grants within a zone (putting the mountain ranges seperating each zone aside) in TBC.
The Classic zones, for the most part, are relatively even surfaces surrounded by a mountain range, there are rarely geographical features right in the center of a zone that are a massive hassle to get around.
Noteable exception is Azshara, but that's ironically one of the least relevant zones in all of Classic.
And that's not even addressing the elephant in the room, which is content that flat out does not work without flying in TBC, installing teleporters / flightpoint to areas that cannot be reached without flying don't work that well.
