Southwest Airlines which bought AirTran on May, said that the pilots of both airlines have reached a tentative agreement on seniority, which would require the approval of the members of each company.
Southwest plans to fold AirTran, therefore to become a single airline, which would include AirTran planes and employees in Southwest colors.
When airlines combine, seniority determines which pilots get the best assignments and which gets more pay. That can be a sticking point in airline mergers.
A previous deal was scuttled when AirTran leaders decided not to send members to vote, to which Southwest answered that the unions had agreed to submit the issue of arbitration if they couldn’t reach a deal by October 1.
