As of March 2026, Delta Air Lines generally does not have a weight limit for carry-on bags on the vast majority of its domestic and international flights. The primary requirement is that the bag must fit within the size dimensions of 22 x 14 x 9 inches and that the passenger must be able to lift it into the overhead bin unaided. However, there are three specific 2026 exceptions where weight is strictly monitored due to local airport regulations: flights departing from Singapore (7 kg / 15 lbs limit), Beijing (10 kg / 22 lbs limit), and Shanghai (10 kg / 22 lbs limit). For all other routes, Delta prioritizes size over weight. In 2026, travelers should still be mindful of "Basic Economy" restrictions; while Delta currently allows a carry-on for these tickets, boarding late may result in the bag being "gate-checked" (free of charge) if the overhead bins are full, a common occurrence on the high-load flights of 2026.
