not long ago a retired fedex driver gave me a website for discounted travel for airline employees...the catch is that you have to be flexible in your travel dates...the upside you don't actually have to work in an air operations. all employees qualify (ups, fedex) because both companies own airlines. at least that's what the driver said...i haven't personally tried it.
i'll see if i can find the link and if cheryl doesn't mind i'll post it.
