Another example from today. Mrs radeng is in Singapore on business, and has had a trip to Bangalore tacked on at the last minute. Silk Air fly direct (the only carrier who does that she has found) for around £300 return. The corporate travel agent in the UK who she is supposed to use 'can't book' Silk Air. They offer a routing taking a long time, costing £1100 and involving a change..........
Not much added value in using them, is there?
