Key differences
Network and hubs
Cathay Pacific runs everything through Hong Kong, serving more than 190 destinations in over 60 countries with subsidiaries and partners. Vietnam Airlines uses Hanoi and Ho Chi Minh City as main hubs, with Da Nang as a secondary hub, and flies to Europe, Australia and the US plus a dense Asian network. Both link Hong Kong with Vietnam; Cathay's own Vietnam page lists Hanoi and Ho Chi Minh City. Vietnam Airlines offers far more domestic Vietnamese connections.
Cabins and seats
Cathay offers Business, Premium Economy and Economy, with First on some 777-300ERs. Refurbished 777-300ERs have Aria Suites and new Premium Economy, and A330s are due to be refitted. Vietnam Airlines has Business, Premium Economy (A350 and 787 only) and Economy. Its widebody Business is lie-flat in a 1-2-1 layout, while the A321 has 2-2 recliners at 45 in pitch. Economy pitch is 31–32 in. On short regional hops, check which aircraft you will be on.
