MINNEAPOLIS — Pilots at Northwest Airlines Corp. say they'll meet with Delta Air Lines Inc. pilots for two days next week to begin working out a joint contract.

The pilot groups tried but failed to resolve their differences before the airlines announced last month plans to combine.

The pilots failed to put together their seniority lists. Those seniority rankings are important because they determine who gets desirable planes and schedules.

A hot line message from the Northwest pilot union says the meeting will focus on a joint contract, with seniority issues to come later.

Northwest pilots say they oppose the deal with Delta because they were left out. Delta pilots support it. The airlines don't need pilot permission to join.
