What size carry-on can you take?

For Delta Airlines one carry on and one small item such as a purse/laptop/briefcase etc is allowed. The carry on must not exceed 45 linear inches in combined length, width, and height.

The carry on must also easily in the Carry-on Baggage Check, which is located near the check-in counters and at the gate and is approximately 22" x 14" x 9". However, experience suggests they rarely check and some passengers break these rules.
