Narrative:

My concern is similar call signs: aac, acc and abc. All 3 departed within 10 mins of one another. I've seen on several occasions, pilots as well as controllers, mixing the call signs. Luckily, they all go sbound. But they need to change one to prevent confusion. This has been brought to the air carrier's attention!
