Conservative columnist Ann Coulter flew into a fit of fury Saturday after Delta Airlines booted her from her reserved “Comfort+’’ seat — which comes with 3 additional inches of legroom — and gave it to another passenger.

In a two-hour tweeting tantrum,she quoted her exchange with a flight attendant: “Why are you taking me out of the extra room seat I specifically booked?’’ she asked.

Their answer, she said, was “I don’t know.’’

The 6-foot-tall Coulter, who is 55, tweeted a picture of the woman who got her aisle seat on the flight from LaGuardia to Florida, noting, “Delta didn’t give my extra room seat to an air marshal or tall person.’’

A Delta spokesman said it appeared Coulter was in the same extra-room row, just in a different seat. But he promised to look into it.

One Twitter user, clearly not a fan of the columnist, wrote. “Ann Coulter is having a bad day which makes my day better. Thanks Delta.”
