US Airways Group Inc.'s stock started to taxi last week and then took off after the nation's sixth-largest airline averted a strike by mechanics and cleaning crews.

The looming strike had caused operating problems for the airline and had hurt September passenger revenue, pushing US Airways stock to less than $25 a share for the first time in 2 1/4 years.

The stock began to rebound early in the week after a tentative settlement with the machinists union was announced, then climbed to $32.75 Friday after the settlement was approved by rank-and-file members.

Also elevating the stock was the announcement Thursday that US Airways will be able to increase its flights -- and passenger capacity -- by as much as 10 percent next year when it takes delivery of new planes and clears up some long-term operational problems.

The increase in US Airways shares set the pace for a big rebound by stocks of companies based in the District, Maryland and Virginia. The Washington Post-Bloomberg regional stock index reversed five consecutive weeks of losses by gaining more than 2 percent to close at 165.31.

Analysts' endorsements helped two of the weeks' other big winners, CyberCash Inc., the company that handles payments for Internet shopping, and Capital One Financial Corp., the credit card company.

Capital One's shares jumped $8 after Solomon Smith Barney Inc. told investors that the stocks of credit card companies have been overly battered by fears of higher interest rates, making this a good time to buy.

CyberCash shares gained more than $1.50 after two analysts recommended the stock, saying it should benefit from heavy online shopping during the holiday season.

Online business already is booming for Arlington-based Telebanc Financial Corp., which said it had become the first pure online bank to hit $2 billion in assets. The announcement added $4 a share to the stock price of Telebanc, which is to be acquired by E-Trade Securities Inc., the big online brokerage firm.

Early warnings of waning earnings crushed the stocks of Sunrise Assisted Living Inc., the Virginia-based chain of homes for the elderly, and Strayer Education Inc., the District-based chain of business schools.
