After the Eastern Airlines strike in March 1989, the company rebranded the PBA/Bar Harbor flights in New England and Florida from Eastern Express back to Continental Express, practically overnight, in order to keep the routes flying. Continental ticket stock was shipped out to the stations, and Continental trainers were deployed to teach the Eastern Express ground staff how to use Continental's reservations/check-in systems. As Eastern came back to life, the parent company decided to operate the PBA/Bar Harbor routes under what may have been one of the first dual codeshare agreements in the airline industry. Flights were now branded as both Continental Express and Eastern Express, and were sold in both systems under both the EA and CO airline codes. Employees joked about how long it took to answer the phone ("thank you for calling Continental Express/Eastern Express/Bar Harbor/PBA").
