American Airlines management has agreed to restore about $81 million in annual pay raises to flight attendants lost when members last month defeated a tentative contract by 16 votes out of 16,000 cast. American flight attendants' negotiating committee met Thursday with CEO Doug Parker and other executives who agreed to revise the contract imposed in arbitration last week. The 6.5 percent higher pay gives American's 24,000 flight attendants "the highest hourly rates among our network peers," the company said in a statement. The pay scale, effective Jan. 1, includes a top hourly rate increase from $50.17 to $53.52. - Linda Loyd
