“As pilots look at the components of the proposal, there may be some who describe it as concessionary,” American said on its website. “The reality is that in virtually every area of the proposal, we have offered industry-leading terms.”

To help resolve differences, American offered two options on pivotal points such as compensation, productivity, pension and benefits.

Under one of American’s proposed pay plans, pilots would get a 4 percent average raise on the date the contract is signed, followed by a 3 percent boost after 15 months, and increases of 2 percent after 30 months and again after 45 months.

The second option offers a 5 percent average increase at signing, followed by a 4 percent jump after 12 months, a 2 percent increase after 24 months and 3 percent after 36 months.

Pilots had sought a 10 percent signing bonus, followed by 7 percent raises in each of the next three years.
