JetBlue Airways has replaced all of the flight hour maintenance agreements it had with Aveos Fleet Performance, which abruptly ceased its Canadian operations in March, and the low-cost carrier says it negotiated new deals that are expected to increase maintenance expenses by only $8 million next year. That is less than carrier says it originally expected.

The Aveos agreement covered about 20% of the components on JetBlue’s Airbus aircraft, and JetBlue has been using time and material providers at greater cost as an interim measure.

During JetBlue’s Oct. 25 third-quarter results conference call, the airline also said it is finalizing maintenance agreements for Embraer 190 components.

The New York-based carrier offered some additional details on its growth in Boston, where it will offer as many as 109 daily flights this quarter. CEO Dave Barger says the carrier is “committed” to as many as 25 gates in Terminal C at Boston Logan International Airport.

JetBlue reported a $45 million profit for the third quarter, up from $35 million in third quarter 2011, on a 9.4% increase in revenue to $1.3 billion.
