United

Allowed dimensions: 56x35x23 cm

The context in a few words

United is one of those carriers from Dominique that locals know well. The network is contained, the fleet modest, but the carry-on policy stays close to industry references.

56x35x23 cm: well within norm. No upside surprise, but no nasty ones either, provided your declared bag matches what passes under the gauge.

On the ground, posted rules and counter practice don't always align. United publishes 56x35x23 cm, and gate agents typically allow 1–2 cm of leeway before routing to hold. Don't bank on it — tolerance evaporates the moment the flight fills up.

On this kind of carrier, aircraft can be smaller — turboprops or regional jets. Overhead bins follow suit: a slightly oversized bag may be redirected to the hold at the foot of the stairs, free of charge but with a delay on arrival.

Don't overlook the allowed personal item — it's often the trick that saves a light trip. Handbag, laptop sleeve or small backpack, as long as it slides under the seat in front. On United, that's where books, headphones, water and flight essentials live without eating into the main carry-on.
