American Airlines flight attendants are planning to picket at 10 airports around the country today, including in Boston, to protest millions of dollars in executive compensation being awarded even though flight attendants have taken a pay cut.

The flight attendants, who agreed to $340 million in annual concessions in 2003 to help the struggling company — it was the only major US airline to lose money last year — are protesting the approximately $100 million paid to top executives in the past six years.

American Airlines says this money is “variable compensation’’ tied mainly to stock performance that makes up 75 percent of executives’ salary. In the past 10 years, executives have been paid only 65 percent of their intended compensation, according to the company.

“American’s executive compensation plan directly links pay to the company’s performance and places a significant portion of management compensation at risk,’’ an American Airlines spokeswoman, Susan Gordon, said in a prepared statement.

About 40 Boston-based flight attendants plan to be part of the protest outside of Terminal B at Logan International Airport.

Among them is Meghan Corrigan, 37, who said she is flying an extra 40 hours a month to make up for her 33 percent pay cut.

“We’re all upset by it,’’ she said of the money executives are making. “I want my company to live and survive with some accountability.’’

The Association of Professional Flight Attendants, the union that represents American flight attendants, has been in contract negotiations with the airline for nearly three years.
