Hate to break it to you, but mainline carriers could care less what your payrates are. It doesn't affect them whatsoever. Lots of information is included in an RFP bid, but very little of it is relevant to the final decision made by the mainline carrier. Many Air Service Agreements (or Capacity Purchase Agreements, etc...) include a clause that states the mainline partner will cover labor costs up to and including the industry average. If the employee costs go over the average, then the mainline carrier doesn't cover it. It comes out of the regional's profits. Because of this, labor costs are irrelevant in an RFP. All that matters is ability to meet performance targets and total bid cost.
