Stephen Amell was forcibly removed from a flight in Texas — this after allegedly screaming at his wife in front of a plane full of passengers … TMZ has learned.

Sources close to the situation tell us … the “Arrow” star was escorted off a Delta flight Monday in Austin around 3 PM, following a shouting match with his wife, Cassandra Jean.

We’re told Amell appeared intoxicated, and that his wife ended up burying her face in embarrassment. Our sources say a flight attendant had asked him repeatedly to lower his voice, but he refused … until eventually, an air marshal and 3 other attendants had to give him the heave-ho.

We’re told his wife and their companions ended up flying back to L.A. without him … while Stephen was at least detained in Texas. It’s unclear what happened — if he was arrested or released — once they removed him from the plane. We’ve called the local cops and Stephen’s reps … but no word back from either.

It seems he and Cassandra were in town for an appearance at the ATX TV Festival. Cass posted a photo of them on a stage over the weekend, and they looked chummy. Obviously, things went sideways on the way home.

A Delta rep confirmed their flight was delayed due to an unruly passenger, but wouldn’t comment further about Stephen or any possible charges.
