Light fares will always have a 'B' in second to last character of fare basis codes. Both Light and Standard fares will simply show as "Economy" class in the ITA itinerary listings. If you are thinking "Economy" is the same as "Standard", it's not.


ExpertFlyer is pretty useless here as they have point-of-sale inventory issues with roundtrip searches. They always use EU point-of-sale for return flights even when trip origin is US/Canada and they should be using US/Canada point-of-sale inventory. Expertflyer is showing no T inventory on return flights even though there clearly is availability on them from US/Canada point-of-sale perspective. ExpertFlyer is only showing H class inventory availability on flights. I've sent a bug report to ExpertFlyer, but they never responded.
