Some stubborn smokers forced a Sunwing flight traveling from Halifax to the Dominican Republic to land in Bermuda.Once they touch down in Bermuda police boarded the plane and arrested three passengers.'It appeared to be a father, a mother, and a son. The parents appear to be in their 50s. The son, I believe, is around 22 or so,' sad acting Insp. Paul Simons.The family has been ordered to stay in Bermuda and their passports and travel documents have been confiscated.Passengers inconvenienced by the unscheduled stop were given hotel rooms and boarded a new flight Saturday.'Seems there people didn't get the memo about not smoking on flights anymore and the fact that you have to listen to the instructions of the crew,' said a post on airliners.net, the 'biggest and most visited aviation interest site on the Internet.'Sadly, this might not be the last inconvenience for Sunwing passengers.A strike could in effect soon, said CUPE, the union representing the company's 900 flight attendants.'On March 2, sixty days after the start of the conciliation period, the flight attendants' union will have the right to strike,' CUPE wrote.'At that time, the conciliation period can be extended with the consent of both parties. But as things stand now, the union doubts that it would agree to an extension.'The union of Sunwing flight attendants is negotiating its first collective agreement.
