Amadeus responded to Lufthansa's announcement to introduce a surcharge of 16 Euros per ticket for tickets booked using a global distribution system. The response suggests there would be no financial impact. This suggests any decreases in volume will be compensated by an increase in the charges. It also implies that the ratio of Amadeus' bookings per ticket is high at about 2.7. T2RL believe this indicates that on average Lufthansa is selling complex connecting itineraries through the GDS rather than simple point to point itineraries. It also suggests that the average booking fees have risen by about 2.5-3.0% since 2008 as the surcharge rate at that time was published at 4.90 Euros.
