I normally don't fly a ton on the 757s, and they always seem different when I do. I know that Delta has several configs of this bird and was wondering how people figure out which it is. I tried a few things and can only figure out that it said 75Q, but I dont know which that is...

I am flying this sat from ATL to SJD direct and cant figure out if this bird has AVOD or not.

Thanks in advance.
