The episode happened in Puerto Rico last May when the plaintiffs and a third female crew member, who is not a party to the lawsuit, were on an overnight layover in San Juan after working a flight from Washington, the lawsuit said.

After checking in to their hotel, the women went to the beach, where they noticed two men nearby who were drinking beers they had brought in a lunch bag, court filings said. The group began chatting and soon realized they all worked for JetBlue.

Mr. Johnson handed a beer to one of the women, who drank some and passed it to the other two, the lawsuit said. “The beer was laced with a drug, and after that point, the rest of the night became a blur,” the lawsuit states.

The lawsuit said that after the women became incapacitated, the pilots took them to the InterContinental Hotel. Neither plaintiff could remember leaving the beach or how they got to the hotel, the lawsuit said.

Mr. Watson took Jane Doe 2 to her room but did not rape her because she was vomiting from the drugs, which he found to be “a turnoff,” the lawsuit said. Mr. Watson left her room “after having been scratched” but was accused in the lawsuit of drugging the woman “with the intent to rape.”

In court filings, Jane Doe 1 said her first memory after being on the beach was of Mr. Johnson raping her while her co-worker, the third woman, lay beside her. Court filings said Jane Doe 1 “felt the influence of the drug” but “was unable to react to the situation” and “was simply aware that it was happening.”

The lawsuit said that after Mr. Johnson raped Jane Doe 1, he raped her co-worker and then told the women, “Thank you for making my fantasy come true.”
