I understood flyerCo’s post as saying that if an item is special (being defined into a specific category on delta.com) and has an associated fee, then that fee applies to everyone regardless of dimensions. Examples of these are antlers, surfboards, and bicycles. If you have any of these, then it doesn’t matter if they weigh 20 lbs, or if you have Medallion status, Delta can still charge you according to delta.com. Excess weight/size fees are separate from the special item fee.
