Flights from Hong Kong to Southeast Asia: the best tips from KAYAK users

Insights shared by verified travellers who flew the route from Hong Kong to Southeast Asia 
Verified travelerFlew with Singapore AirlinesHKG-SINApr 2025
Go to the airports early if they have time cause both Hong Kong and Singapore Int’l Airports have wonderful/spacious shopping arcades where you can roam/window-shop/shop around, and enjoy a vast variety of Asian and western cuisines!
PaulFlew with Cathay PacificHKG-CNXNov 2024
CX Flight number but the carrier is LCC Hong Kong Express which means no meal and no drinks at all without paying. Not even water. So keep your credit card handy so you can buy a drink if you get thirsty. Seating is LCC cramped and basic. No IFE. Gate was the furthest possible gate in the satellite terminal at HKIA so allow time to walk there.

signage could be better in locating transfer departure gate when you are coming off of a transiting flight. Airport has lots of amenities

The food and service was great. You have to pay a lot for in flight Internet though which is lame.

The food and service was great. You have to pay a lot for in flight Internet though which is lame.

Special request meals are really below average. Vegetarian options are very limited if you didn't prebook.

I have a Peanut Allergy and the Steward staff were very accommodating in ensuring my safety as my allergy is life threatening. Very professional and so vested in their profession.

Everything was fine and I have no complaints or things to note.

The flight was delayed for 30 mins. The overall experience was good.

Overall, it was ok. However, the food was very sub-par.

Baggage delayed for 2 days and still chasing for reimbursement of basis items. Very horrible customer care service.

Horrible. No good food. Baggage missed to onboard and came after a day. No support to compensate the delay. Customer care cannot see the status of the complaint. No reply of the email.

bad… no veg food was provided eventhough i pre ordered special meal

Cathay has a great reputation, though it's baseline economy seating is nothing to write home about (and SE Asia flight passengers sometime lack 'routine stateside' etiquette). On the other hand, food was great, flight attendants were nice, and price was very good~
