Yeah I'm curious as to who the target market is here....for pax looking to get to/from BLR and N. America, Emirates, Qatar or Lufthansa would be clear superior options (DXB, DOH, MUC and even FRA are much better hubs than ADD). So if it's not N. America pax, then is there really that much BLR-Africa traffic?
I second the comments about the 737. ET's 767 to/from Delhi is awful too (at least in Economy). I love the ET A350s and 787s though.
