Fabulous airline .booked last week for business class return to Singapore with a 24 hour stop over in Istanbul. Did the same trip last year. One of the best business lounges in the world.
Airport huge..transfer on the way back from gate with wheelchair service took more than 50 mins.
Gave up on BA and KLM a long time ago.
Website last year was a pain but this time went well.. possibly depends on your operating system and broadband speed.
