Analysis: In March, American Eagle posted healthy year-over-year growth in traffic, capacity and load factor. The largest U.S. regional also experienced solid growth in traffic, capacity and load factor over February 2006.

Analysis: Comair in March suffered traffic and capacity slips year-over-year but posted a 4.1-point gain in load factor. In comparison to the figures posted for February 2006, however, it has reported healthy improvements in all three sectors. Delta's bankruptcy continues to weigh heavily. Flights through Cincinnati, Comair's home base, have been cut back.

Analysis: In March, Delta Connection partners continue to log more miles for Delta because its partners, particularly Shuttle America and Freedom Airlines, have been flying more routes since October. Its performance over February 2006 continued to see marked improvements in all factors.

Analysis: ExpressJet's traffic and capacity continue to significantly increase for its Continental Express fleet year-over-year and over the February period. Continental pays the regional for completed block hours. In February, ExpressJet took delivery of one 50-seat Embraer ERJ 145XR, bringing its total operating fleet to 270 jets.

Analysis: Horizon posted solid jumps in RPMs, ASMs, load factor and enplanements from the year-ago period. It also posted significant gains over its February 2006 performance. Horizon has been flying as a code-share for Frontier Airlines for two years now.

Analysis: Jazz's remarkable growth in both the year-ago period and from February 2006 continues. The airline benefits from Air Canada's growth which saw record load factors for the 24^th consecutive month. The major carrier cited its new business model centered on simplified fare structure, product innovations, a strong economy and strong customer service for its success.

Analysis: Mesa's traffic and capacity jumped from the figures posted in February 2006, just as it did from the March 2005 period. The airline continues to curtail its US Airways Express flying in favor of continuing its America West contract and devoting more aircraft to Delta and United.

Analysis: Flying as Northwest Airlink, Pinnacle is managing to perform well despite slight dips in year-over-year capacity and block hours as planes returned to their lessors. However, growth in RPMs, load factor and enplanements, remain strong as well as from the February 2006.

Analysis: US Airways Express' in-house carriers' capacity growth has slowed down for several months in a row now, following expansive growth. In February, ASMs were actually down 8 percent year-over-year. The code-share operations of US Airways Express and America West Express are not reported.
