I used their service in Dec 06 and found them to be somewhat unprofessional (woke me up at 4:30 AM for a 5:00 PM pickeup...driver mixed up AM/PM). This was tolerable. In march, I noticed two new charges from ABCO Airport Service for the exact same amount as my Dec. trip. I definately did not use their service (or one of their partner services) as I was out of the country for this month. After endless promises of a refund, nothing ever showed up. My credit card company (Citicard) claims that it is not their problem either, leaving me stuck with two 60$ fraudulent charges. Avoid this service!
Cons: fraudent duplicate billing
