A 29-year-old woman endured a shocking violation during a long-haul flight when a fellow passenger allegedly touched her inappropriately while she slept. The incident, which unfolded in the first-class cabin, left her shaking and crying upon learning of it from crew members. Authorities quickly took action upon landing, highlighting ongoing concerns about passenger safety at 30,000 feet.[1][2]
The Assault in First Class
Guillaume Sebastien Roger Mattler, a 48-year-old French resident, sat next to the victim on Swiss International Air Lines Flight LX64 from Zurich, Switzerland, to Miami on April 28. The two exchanged brief pleasantries before she turned her back, curled up, and fell asleep halfway through the journey. Witnesses later reported seeing Mattler reach across the armrest, first touching her lower back as if his hand had slipped, then progressing to more invasive contact.[1]
One passenger observed a “submarine” motion, suggesting an attempt to slide his hand under her clothing or between her legs. A flight attendant intervened after another witness alerted the crew and captured video evidence. The attendant saw Mattler’s hand on the woman’s crotch over her jeans, making a scooping or rubbing motion on her vaginal area. The victim remained asleep throughout and had no prior connection to Mattler.[2][3]
Crew Intervention and Victim’s Reaction
Flight staff confronted Mattler, who could not demonstrate any acquaintance with the woman. They promptly relocated him to the economy section to separate the parties. Later, when crew escorted him back to retrieve his belongings, he attempted to pass her a handwritten note. The attendant woke the victim at that point and explained the situation.
She confirmed she did not know Mattler and reacted with visible distress, shaking and crying as the reality set in. At least three witnesses, including two passengers and the flight attendant, corroborated the account, with video footage supporting their observations. This swift response by the crew prevented further interaction and ensured the woman’s safety for the remainder of the flight.[1]
The Note and Post-Flight Interview
The note, scrawled on Mattler’s business card, read, “You look beautiful when you are sleeping,” and included flight details along with his seat number. In one account from authorities, he referenced it slightly differently as “you look cute when you sleep.” This attempt to contact her came immediately after the alleged assault, adding a layer of unease to the episode.
Upon landing at Miami International Airport, U.S. Customs and Border Protection officers interviewed Mattler in an audio-recorded session. He initially denied any touching but changed his statement after learning of the witnesses and videos. Mattler admitted he had touched “whatever he could reach from across the arm-rest” and described it as not a big deal. He claimed his original intent was simply to obtain her phone number and deleted photos from his phone during the process.[2]
Federal Charges and Custody
Federal authorities filed a criminal complaint on April 29 in the Southern District of Florida, charging Mattler with one count of abusive sexual contact. He made an initial court appearance shortly after and remained in custody at the Federal Detention Center in Miami. Prosecutors sought pretrial detention, citing him as a flight risk and danger to the community.
Mattler declined assistance from the French consulate. A detention hearing was scheduled for early May. The case drew from detailed witness statements and video evidence, underscoring the role of vigilant passengers and trained crew in addressing such incidents.[3]
This episode serves as a stark reminder of the vulnerabilities travelers face on flights, even in premium cabins. While airlines and authorities responded effectively here, it prompts questions about prevention measures for frequent flyers sharing close quarters mid-air. The outcome of Mattler’s case may influence how such complaints are handled in the future.
