For the past month or so matrix.itasoftware.com seems likely to return a very incomplete list of flights, even for very simple queries.

e.g. "One-way: Los Angeles to DFW, ORD, SEA, PDX, YVR, YUL, Thu, Aug 10" returns just 10 flights, and the only AA flight is to PDX.

Qualifying the carrier with AA+ returns 8 AA flights, including one to DFW but none to ORD.

Specifying just ORD as the destination (still AA+ for carrier) returns 10 AA flights.

Removing the carrier specification returns a total of 9 flights LAX-ORD, two of which are AA.

Not seeing a general outcry, I suppose I'm the only one with this problem, but it makes the tool essentially useless. Any thoughts?
