I'm doing the BA15 route with MasterBR, and our approach is to take a room at the Rydges Hotel at the airport from the preceding night so we can check in immediately, and then use the first day as a rest day. As we're on a redemption and guffed into F, the cost differential to booking QR or other easily pays for the room.

Actually on this subject, is BA15 regarded as a separate flight from the point of view of catering? What is the meal service on SIN to SYD? I'm very familiar with the BA11/15 to Singapore, but wondering whether to grab something to eat in Changi as well as grabbing a shower.
