We are traveling on Saturday with a group of 13 from DFW to BLQ via EWR and FRA. My 15yo daughter has developed a painful condition in her feet called fasciitis. So I asked the travel agent to order wheel chairs for her at the airports.
He told me that a Skycap will "drive" the wheelchairs. In the US, "Skycap" usually translates into tipping. So I asked, and the travel agent said that would be a good idea.
