Linear Air's 2nd aircraft N575CC seems to have had a lot of downtime in ABQ for maintenance lately.
It was back in ABQ from 3/27 through 4/8 this year and then from 5/1 through 5/6. That's more than 2 weeks downtime, not to mention the cost associated with two flights back and forth across the country.
Linear Air's 1st aircraft shows no records of having flown since the middle of March.
