ABCs of Airport Call Letters

Ever wonder why Chicago airport call letter is ORD or for that matter Columbus, Ohio airport call letter is CMH? I thought ORD stands for O'Hare Regional District.. But that is not the case.. Of course, I could never figure out what CMH stood for until now..

I looked around to understand why Chennai airport identification code is MAA, but couldn't find any.. Do you know?

    CMH - Columbus Municipal Hanger
    ORD - from ORcharD field

  4. could it be that they wanted to allot MAD, but that was taken by Madrid. They might have settled for MAA.

    That is possible.. MAdrAs => MAA

    Interestingly, the first time I was returning from US, the agent in Columbus sent my bags to MAD instead of MAA and it took me a week to get my baggage.. (Chennai used to be called Madras then..)
