An interesting and thorough summary.
While loads are still challenging airlines, capacity has been reduced so that is feeding through to keep fares more stable than was the case last year.
Meanwhile, APD taxes continue their relentless rise (currently £434 on an exLON J rtn to SYD, and set to rise again in November!!), oil is not getting any less expensive and there are fewer super prmium fully flex fares being purchased, which makes it less easy to discount.
I think Finnair have some deals on right now, if like the cold.
