Park in economy to save $2 a day, get a space far away, decide it isn't raining that hard, don't take your umbrella, put on winter coat, get soaked on way to covered walk !!
don't buy an iphone 5 usb cord from the "i-store" or whatever it's called. $32 and it tore when i got to my gate. luckily i got my money back on my return flight.
This airport is huge! so don't waste your time until you localize your gate. If your fly is canceled don't forget to ask if they offer a free/better rate hotel.
AVOID this airport for connection flights at all cost! Extremely disorganized, seems like all flights go to the same control points, 2+ hours to go trough 3 control points with people shouting at you.
Hartsfield-Jackson Atlanta International Airport proudly bears the distinction of being the world’s busiest and most efficient airport and has served as a valuable hub connecting various cities and countries around the globe.
