I have found that the "taxes and fees" for an Avios award ticket are sky high like many - more than 5 x - times higher than a similar award ticket on United or Lufthansa. Part seems to be London landing fees - but I am connecting directly. (But I have connected via London on United too.) Is there any way around this? (Seems to make BA award tickets pricey compared to other programs.) What have other people found?
