A Thomson Airways flight was delayed after passengers noticed a personal Wi-Fi hotspot called ‘Jihadist Cell London 1’.
Flight TOM039 was set to depart Cancun, Mexico, for Gatwick on Tuesday, a day after the suicide attack that killed 22 including children in Manchester.
After the crew urged the culprit to come forward, a full security search was carried out. Some passengers refused to stay on board and the flight missed its take-off slot.
A Thomson spokeswoman said: “We would like to apologise to our customers who were delayed, due to a potential security concern raised before take-off.
“A full security check took place as a precautionary measure on the aircraft and we made arrangements to reschedule the flight and return customers home as quickly as possible.”
