JetBlue holds the crown for the most nonstop destinations from Boston's Logan Airport.In 2020, the airline said it plans to increase service to more than a dozen cities it already services, with nearly two dozen flights between Boston and New York each weekday. The airline appears to be going after business travelers by expanding nonstop service between Boston and New York's LaGuardia Airport. The airline intends to offer up to 10 daily round trips on the key business route by spring. JetBlue says the expanded service to LaGuardia, combined with service to Newark Airport and JFK Airport will result in up to 22 daily flights to New York’s three airports from Logan.The airline is facing stiff competition for business travelers from both Delta Air Lines and United, which both offer similar frequent service to New York's major airports. In addition to New York, JetBlue said it will phase in added flights in 2020 on more than a dozen routes, coast to coast between Boston and these airports:Austin–Bergstrom International Airport (AUS) Charlotte-Douglas International Airport (CLT)Chicago’s O'Hare International Airport (ORD)Cleveland Hopkins International Airport (CLE)Denver International Airport (DEN)Detroit Metropolitan Wayne County Airport (DTW)Los Angeles International Airport (LAX)Nantucket Memorial Airport (ACK)Newark Liberty International Airport (EWR)Philadelphia International Airport (PHL)Phoenix Sky Harbor International Airport (PHX)San Diego International Airport (SAN)San Francisco International Airport (SFO)Mineta San Jose International Airport (SJC)Seattle–Tacoma International Airport (SEA)Ronald Reagan Washington National Airport (DCA)The move comes as JetBlue faces fierce competition from Delta on many of its routes from Logan Airport. Each airline is racing to offer customers an increasing number of non-stop departures from the airport. In 2020, JetBlue says it will offer upwards of 180 daily departures from Boston Logan.
