Boeing has some serious problems at the moment, it has half the orders of Airbus going forward, no replacement for the 737 within at least the next 10 years and on going production issues. Even with half the orders of Airbus they are only producing half the amount of aircraft, which means you will still get your Airbus in about the same time frame as a Boeing, giving them no real time advantage.
Airbus meanwhile has a modern, cross-crewable, contiguous line of aircraft from the 100 seat to 500 seat market. Meaning if you were seriously concerned about operating costs they would be the only ones to go to.
How they are going to dig themselves out of this hole they've made them selves is anyones guess.
