Lauren Beaumont-Capps, 40, who downed six alcoholic drinks on the flight, yelled: “Get me off this f***ing plane.”
She and another drunk female demanded to disembark immediately after it arrived in Manchester from Turkey in January.
The pair were talking “loudly and inappropriately” and “shouting in an aggressive way”.
One crew member said she felt she was going to be physically attacked as Beaumont-Capps called her a “f***ing c***”.
She used similar language with cops and “refused to cooperate”.
And when she was told to stop swearing by a female member of cabin crew, she replied: “You can’t tell me what to do.”
Beaumont-Capps, from Swinton, Gtr Manchester, admitted charges including being drunk on an aircraft.
She will be sentenced next month at Manchester crown court.
