They can still do ZEDs without that NWA travel number that nobody knows. I ran into an agent who said she couldn't help me unless I have her my 6 digit employee number. I kept telling her my employee number, nor any body elses at Mesaba is 6 digits. Finally, when she got snotty and rude I hung up. I called right back, talked to a different agent and had no problems with just providing my 4 digit employee number.
