I think the FNF should be KDEN or KATL because United and Delta has a lot of the 757.
That is true but remember the 757 hasn’t actually been released fully and I don’t think there is a release date set yet.
Hello, unfortunately requests are not accepted for fnf ideas. Although looking at the ATC schedule for the week, The U.S. is featured so there could be a fair chance to have ATC at either of these big airports.
Your suggestions are noted, though check this out for information on how the schedule is made.
