Did an immediate turnaround in CMB on CX last week. Was able to get my return BPs already in SIN, despite being on a separate booking. During checkin in SIN the return flight from CMB flight was somehow not yet open in the system, but the CX supervisor issued the ex-CMB boarding pass then at the gate shortly before boarding. He was quite confused and couldn't understand why I would fly back on the same aircraft again:
"What? You're flying straight back...okay?...never had this before. Well, you must love CX"
Turnaround was pleasant, regarding lounge in CMB I suggest the Lotus First Class lounge as it's much quieter there compared to the Business Class lounge. Flights in general were fine, well, two standard red-eye flights and not the best seats for sleeping (regional configuration).
