Since this is the first time I am ever travelling on an airplane I would like to know what to expect when I arrive at the airport. Literally every single step, because I am totally clueless about where to go, what items to put where, what moniters to look at, ect.

I will be travelling with Delta airlines from Toronto, to Atlanta, then to Aruba (Divi villiage golf and beach resort). We are flying coach. Our departure time is 6:30 a.m.

Sorry I cannot help you with departure from Canada

But when departing from Aruba, assuming you will be again flying through Atlanta, you will find this information below useful.
