They offer just chartered service right now, not scheduled. At least, it's not published in Sabre yet. Visit
www.usa3000airlines.com for more information. This airline is *not* related to Canada 3000, Canada 3000 was strictly a Canadian airline. This airline is based in PA and operated primarily from PHL, EWR and ORD to CUN and PUJ with three A-320s. I think they plan to have five total by the end of the year. The president of the airline, Angus Kinnear, was president of Canada 3000.
They are hiring Spanish-qualified flight attendants to be based at EWR, though. Check out the "Careers" portion of their website. I also still think they have a GM for PUJ posted, as well, but am not certain.
I know AIRWAYS magazine will have an article on them in September -- look for it then!
