This is absolutely correct. Airline profit is in platinums (or the equivalent at other airlines eg. Emerald oneworld) and these people are way and above the most important customers. They are typically your mid-level road warrior and consequently only get to travel in economy class. The 'business class = important customer' is not quite as valid as it first sounds.Ok so maybe that didn't make sense - the bit I was quoting said that people who flew a lot in economy mattered more to Qantas than people who flew in business
