Aware of that and refer to those that avoid UK major airports to get cheaper tickets via a EU destination even if they consequently travel via the UK. Airlines market that way to increase load factors on routes into their hub. Recently quoted a cheaper flight to Oz on PAL from HKG than from MNL on the same flight from their hub. It will be interesting how IAG price fares on their “new” longhaul airline from Barcelona? That maybe a new subject?
