Airlines and Hawaiian Airlines replaced their nonstop services to Hawaii. In the same year, Volaris began service to OAK as their first destination in the San Francisco Bay Area and held a commercial agreement with Southwest Airlines, until its merger with AirTran Airways in 2011. Malaysia-based AirAsia X honored its new partners, the Oakland Raiders of the National Football League (NFL). AirAsia X had one of their planes full of its executives and crew members "touch down" at OAK in acknowledgment of the to-be announced sponsorship. AirAsia executives had new optimism that service between the U.S. and the airline's main base in Kuala Lumpur, could possibly happen earlier than originally expected, but has yet to come to fruition as of 2020. In 2009 OAK had the highest on-time arrival percentage among the 40 busiest North American airports. In 2011 Spirit Airlines returned to OAK after several years of absence, eventually flying a combined total of seven year-round and seasonal routes by the summer of 2017. Oakland International Airport also celebrated its 85th Anniversary in 2011, commemorating the first transpacific crossing by air from OAK to Hawaii, which took place on June 29, 1927, in The Bird of Paradise, flown by Hegenberger and Maitland. In 2012 United Airlines pulled out of OAK, consolidating operations at San Francisco International Airport, its Bay Area hub. Arkefly (which later re-branded as TUI Airlines Netherlands) chose OAK as a San Francisco Bay Area gateway, flying twice-weekly to Amsterdam, via a stop at Los Angeles International Airport. Arkefly provided 18 weeks of scheduled service in the summer of 2012. The airline followed with a similar schedule during the summer of in 2013, before discontinuing service at OAK. In 2013 FedEx Express opened a $30 million upgrade of its hub facility at OAK, including additions to accommodate the airline's new Boeing 777 Freighter fleet. In 2014, Norwegian Air Shuttle announced its first two year-round flights to Stockholm and Oslo airport, using Boeing 787-8 aircraft seating 291 passengers operated by Norwegian Long Haul. The flights were the first-ever nonstop services offered from the two Scandinavian capitals to the San Francisco Bay Area, providing several connections throughout Europe. The Oslo flight was later changed to a seasonal schedule. A long-proposed extension of the BART system to the airport opened on November 22, 2014, allowing passengers to board BART people mover trains and transport from the BART Coliseum station platform
