"How can you NOT keep your requests simple??? All you are allowed to bid, is either one block of up to four days off OR one flight"
I don't know what you are getting at EY. At EK we had about 30 or 40 bid choices. I think you may be getting a roster request system wiht limited choices, versus a PBS, which is what I used at EK. We had a seniority based system with a rotating seniority list.
I've used request systems before in a previous life...
With your growth, AIMS would not be able to keep up.
