Lehman Ups Northwest, AirTran Ratings

Analyst Gary Chase says these air carriers' stocks are undervalued; Northwest shares took a big hit after SARS

Lehman Brothers upgraded Northwest Airlines (NWAC ) and AirTran (AAI ) to overweight from equal-weight, and downgraded Delta Air Lines (DAL ) to equal-weight from overweight.

Analyst Gary Chase sees the beginning of a gradual, but powerful airline upcycle. He says two well-managed carriers, however, have underperformed the rest of sector: Northwest and AirTran.

Chase thinks SARS fears have dampened enthusiasm for Northwest shares of late; while heavily exposed to Asia, he believes Northwest will not suffer permanent damage from SARS; he fully expects shares to close the gap with the rest of the sector.

Also, Chase says AirTran is a very well-managed low-fare carrier with a lot of valuation upside on continued execution. He has a $16 target for Northwest, and a $13 target for AirTran.
