Similar to Count To Infinity In Pictures, but much more finite.
In order, please (AAA, AAB, AAC, etc.) 
There’s more than a few to choose from to start, but I have to go with the obvious -
Travel With Someone You Trust
AAC — Associação Académica de Coimbra
AAD – SPARS Code for Analog Recording, Analog Mixing, Digital Mastering.
AAG-tv, a Pakistani TV channel
AAI - Airports Authority of India (Nice logo)
Please don’t make me listen to their theme song
Both these seem to be missing pictures of the letters.
That’s why using stock symbols is probably not the best option.
There are more obvious ones, but this looks interesting. A.A.N.
A.A.O. - I like this one. G’Day.
A.A.P.: There must be a story behind the broom symbol.
