The big financial losers in the National Football League strike are the league, estimated at between $26 million and $31 million a week, and the players, with uncollected salaries of $9 million a week.

The economic impact of the players' walkout extends much further, however, to bookmakers, airlines and other transportation carriers, hotels, city halls and vendors.

Although most NFL and team officials declined to comment on the strike or related matters, league sources estimated that weekly receipts from television, gate receipts for 14 games and related income run to about $40 million.

The teams, of course, will not have to pay salaries, which amount to an average of $105,000 per player this year, according to the NFL Management Council. Each player receives one-sixteenth of his salary each week.

Neither side in the dispute has strike insurance. The owners have arranged to borrow $150 million from a consortium of banks in California should it become necessary. The players expect income from some planned all-star games.

Las Vegas gambling sources told the Associated Press that as much as $100 million is wagered on pro football each weekend, including legal bets in Nevada, illegal bookmaking and friendly wagers. About $275 million was bet legally last year on pro football with Nevada's 21 sports books. Sonny Reizner, director of the book at the Castaways, said the books show a gross profit of 4.54 percent.

The airlines figure to miss about $300,000 in revenue generated by the usual 14 weekly charter flights, although there can be a wide variance because of distances involved and method of chartering, by game or season. On the basis of last year's ridership of 20,000 per game, Metro will lose $26,000 every Sunday the Redskins are idle.

NFL teams usually stay at road hotels for two nights. The Crystal City Marriott, home away from home for Redskins opponents, estimated that each visit costs between $3,700 and $6,600, depending on number of functions and size of traveling party.

"It's bad news; I'm going to starve," said Debbie Cooksley, secretary to the director of catering.

The Armory Board will lose between $100,000 and $125,000 a game as its percentage of the gate, parking and concessions at RFK Stadium, according to Bob Sigholtz, general manager of the D.C. Armory/Starplex, which manages the stadium.

Most stadiums contacted said they figured to lose between $100,000 and $200,000 a game.

Sigholtz said that 10 months ago, the stadium operators tried unsuccessfully to get strike insurance. "We were going to consolidate and go for one insurance policy for everybody," said Sigholtz, "but the insurance companies said no."

Sigholtz said that left the stadiums to insure themselves, "but even those premiums were so ridiculous that I don't know of anybody who did it."

He said the premium was based on size of stadium, but about $600,000 was the premium amount on one of the smaller stadiums.

Also down the drain are gross concessions revenue of $100,000 to $140,000 per game and the $26,000 in salaries paid to 300 vendors and 200 concessions stand workers, according to figures supplied by B&B Caterers, which services RFK Stadium.

Sportservice, the Buffalo concessions firm that services stadiums in Milwaukee, Detroit and St. Louis, will lose about $500,000 if the strike wipes out the season, according to Sam Gifford, director of corporate communications.

A number of stadiums allow small groups to operate concession stands and some of those groups will be devastated by the strike. Texas Stadium, home of the Dallas Cowboys, for instance, is owned by the city of Irving, Tex., and many of its concessions stands are operated by small area towns.

"Most of them get 15 percent of the gross of what they take in," said Bert Rose, director of the Texas Stadium Corp., which operates the Stadium.

Most stadiums said they employ between 1,000 and 1,500 ushers, ticket takers, concession workers, parking attendants and other stadium personnel.

The Greater Washington Board of Trade declined to guess how much the strike would hurt hotels and restaurants here. However, Pittsburgh's Planning Commission estimated a loss of $235,000 for each unplayed Steelers home game. The Green Bay Visitors and Convention Bureau said that about $25 million a year was recorded by Wisconsin tourism industries because of the Packers' presence.

The Buffalo Area Chamber of Commerce estimates the indirect effect of the Bills home games on area ecomony is $21 million. The chamber said about 5,600 out-of-town fans attend each game and each spends about $80.

The Chicago Park District, which operates Soldier Field, home of the Bears, said it projects a loss of nearly $350,000 a game and the city of Chicago said it will lose about $86,000 in taxes.

Rep. Mario Biaggi (D-N.Y.) of the House Education and Labor Committee, citing "the drastic loss in tax revenues," introduced a resolution yesterday calling for a prompt settlement of the strike.
