Virgin America acquisition gives Alaska the arsenal to up the stakes against United in SFO
One of the main drivers in Alaska’s pursuit of, and eventual acquisition of, Virgin America was strategically to bolster its position on the US west coast. Alaska is now leveraging its newly strengthened position in San Francisco to broaden its combined reach from the city with Virgin America, adding 12 new destinations from the airport by YE2017.
Alaska is upping competition with San Francisco’s largest airline, United, through its expansion at the airport, breaking United’s monopoly in many of its new planned routes. The growth shows that combined, Alaska and Virgin America are in a much stronger position to challenge United than Virgin America on a stand alone basis.
The new routes offered by Alaska are a mix of small and medium sized markets utilising Alaska’s growing fleet of Embraer 175s and Virgin America’s Airbus A320 family aircraft. Alaska’s new route profile from the airport illustrates the combined airline’s ability to offer more network breadth from San Francisco – through a more diverse fleet that should generate a larger pool of revenue for the company.
Emirates has multiple reasons for cutting back on US capacity
As the most conspicuous and largest, Emirates Airline often takes on its shoulders the increasingly difficult task of defending Gulf aviation. Emirates often single handedly represents the Gulf and "Middle East Big 3", in much the same way as Dubai carries regional geopolitics.
Just as there are significant differences between the Big 3 US airlines who have strenuously opposed the Gulf carriers in the US market, so Emirates is fundamentally different from its peers: it is longer established, has a larger home market and has had a more commercial mandate from the beginning.
Yet Emirates must compete in a market where many others would like a piece of that market. Just as Dubai Inc modelled itself in many ways on Singapore Inc, there are many who would follow the same trail. This does not lead to steady market conditions.
Certainly the policies of US President Trump have hurt aviation and tourism. But Emirates' announcement of a 19% reduction in services to the United States is less about US policies and more about the nature of the market forces that started before Trump was even a serious Presidential contender.
