For an early-morning departure the rule of thumb is simple: plan to reach Antalya Airport (AYT) about 2.5 to 3 hours before take-off. In summer the first wave of flights leaves before sunrise, and check-in, bag drop and security can be busy even at 03:00. Your airline sets the actual check-in and bag-drop deadlines, so look them up in your booking or app before you plan anything else.
Once you know your target arrival time at the terminal, work backwards: subtract the drive time from your hotel, then add a buffer. The buffer covers a slow start at reception, a last-minute search for a passport or a sleepy child who needs an extra five minutes. At night the roads are usually quieter, but quiet roads are a reason to relax, not a reason to cut it fine.
