We called the regular res number - 407-W-DISNEY and told them we were airline employees. They do require that you fax a letter from your manager with particular info (date of hire, employee number, etc.) verifying your employment within 48 hours.
Thanks again for the info..I think this is the number I called last time!! I had to fax two letters though as they did not receive the first one!! It is worth it though as they do give us fantastic rates!!!
