Singapore Airlines and JetBlue Airways have jointly filed an application with the US Department of Transportation to enter into a bilateral codeshare agreement.

Under the proposed codeshare, JetBlue customers will have access to five new cities in Europe and Asia, while SIA customers will have access to 16 destinations in the US.

The two airlines have been interline partners since 2011, and the new expanded partnership will allow their customers to enjoy seamless connections between the two airlines with one-stop ticketing and baggage check in.
