The Delta airlines now want the approvals from both the US Department of Transport and European Commission to operate two daily flights on the Miami and Boston routes.

On the other hand, the American Airline and British airways are trying to make a new combined airline to operate across the Atlantic and the Delta wants the approval before the new combined airline starts its operations.

All the airlines are now seeking for the Miami and Boston routes as the aviation industry has seen some sort of recovery in the recent months. The Gatwick based Delta airline started its flight operations from Heathrow in March of 2008 following the Open Skies agreement by both US and EU.

If Delta wins the slots it will be operating at least ten flights per day. Delta will have to face its rivals on the Boston route such as American Airlines, Virgin Atlantic and British Airways, it will face the same rivals in the Miami route also.

Boston and Miami routes have a huge number of passengers in all the time of a year as Miami is a holiday making place and attracts people for holiday trip and Boston is the gateway of New England.
