Hot on the heels of today’s announcement on a start date for the all-purpose Air Travel Bubble (ATB) between Hong Kong and Singapore, the flag carriers of both cities have rolled out their flight schedules for the quarantine-free flights.
Cathay Pacific says it will be deploying Airbus A350-900 aircraft staffed by pilots and cabin crew who have all been fully vaccinated. Its inaugural quarantine-free service from Hong Kong to Singapore, CX759, will depart on 26 May, while the airline’s first ATB flight from Singapore to Hong Kong, CX734, is scheduled for the following day.
Cathay’s schedule for ATB flights from May 26 to June 8 is as follows:
Flight | Route | Dates | Departure Time | Arrival Time |
CX759 | HKG > SIN | May 26, 27, 29;
June 1, 3, 5, 6, 8 |
09:10 | 13:05 |
CX734 | SIN > HKG | May 27, 29;
June 1, 3, 5, 6, 8 |
14:45 | 19:00 |
Starting on June 10, Cathay Pacific will operate daily return ATB flights to Singapore with the same time slots.

Initially these will be operated aboard Airbus A350-900 aircraft, but the carrier will switch to Boeing 777-300ERs from June onward.
