Quick summary
Taipei Taoyuan’s published minimum connection time is 90 minutes for an international-to-international transfer. Hong Kong International applies a single flat 60-minute floor to every connection type. That gap, not the airborne sector, is what decides which hub suits a same-ticket Asia-Pacific itinerary.
Both figures are guide-level renderings of OAG data rather than airport-published guarantees, and they shield only single through-tickets. The sections below map each hub’s physical transfer steps, Taoyuan’s 2025-26 terminal changes, and the passport exceptions that can stop a Hong Kong transit before boarding.
Taoyuan’s Terminal 3 North Concourse has been handling transfers since 25 December 2025. The main Terminal 3 building is still projected for completion in 2027, so some published terminal maps no longer match the airport you will walk through.
A 60-minute international connection at Taipei Taoyuan sits below the airport’s published minimum connection time.
For Asia-Pacific itineraries on a single through-ticket, that floor drives the hub decision. As of late 2026, the gap between Taoyuan and Hong Kong International is the whole argument. A missed onward flight is the concrete risk. On separate tickets, the rebooking cost is yours.
The published floor by connection type
Taoyuan has four separate minimum connection times. International-to-international and international-to-domestic transfers both carry a 90-minute floor. Domestic-to-international drops to 60 minutes. A domestic-to-domestic connection needs only 30 minutes.
Hong Kong takes the opposite approach. A single flat 60-minute OAG standard applies to every connection type there, with no tier to look up and no arithmetic to do before booking.
The corridor between the two hubs is busy enough for both sets of floors to matter. China Airlines alone runs six daily Taipei-Hong Kong flights and two daily Kaohsiung-Hong Kong services, according to China Airlines, feeding the banked arrival and departure waves at each end.

Inside the transfer: re-screen and people mover
At Taoyuan, a transfer is not a walk-through. Every transfer passenger clears a security re-screen at a transfer counter, a requirement that also shapes how Taipei’s connection floor compares with Tokyo Narita’s.
Terminal moves add another layer. An airside people mover links Terminal 1 and Terminal 2; the landside T1-T2 train that once carried that traffic stopped running on 1 July 2026.
Taoyuan’s North Concourse handled 58,801 passengers during its 1-24 December 2025 trial period.
Exceptions: separate tickets and passport rules
Two conditions break the clean comparison: separate tickets and a terminal change at Taoyuan. On two tickets, both Hong Kong and Taoyuan lose the protection of the published minimum connection times.
A terminal change creates a different gap. Taoyuan’s bare minimum connection time does not account for the extra minutes the airside Terminal 1 to Terminal 2 move adds, so the figure on the booking understates the time the transfer actually takes.
Hong Kong has a passport exception that can stop a transfer before boarding. Airside transit on a single ticket normally bypasses immigration there. Certain nationalities, though, face a visa requirement even when they never enter the city. By the transfer desk, it is too late.
Four checks before the ticket is issued
The published floor is only part of a workable itinerary. Four conditions decide whether the connection actually works.
- Confirm the ticket type. Published minimum connection times shield only a single through-ticket; on two separate tickets, a misconnect at either hub is yours to absorb.
- Match the connection type to the floor. Taoyuan asks 90 minutes for international-to-international, 60 for domestic-to-international, and 30 for domestic-to-domestic.
- Check your passport against Hong Kong’s transit exception list. Airside transit normally bypasses immigration, but some nationalities need a visa even without entering the city.
- Add time for a Taoyuan terminal move. The airside people mover between Terminal 1 and Terminal 2 adds minutes the bare minimum connection time does not cover.
Both floors are stable numbers, and neither airport is. Re-check the connection type on each booking rather than assuming the last itinerary’s answer still holds.

Questions? Answers.
Do I need a visa to transit through Hong Kong Airport?
For airside transit on a single ticket, usually no visa is required. Hong Kong keeps a passport-specific exception list, though, and it applies even to passengers who never leave the terminal, so the check belongs before you pay for the ticket.
How long is the flight from HKG to TPE?
Depending on direction and schedule, roughly 1 hour 45 minutes to 2 hours. Because the sector is short, connection timing rather than airborne time is what drives the real itinerary decision.
Why are there so many flights between HKG and TPE?
The route is a major short-haul business and transit corridor served by multiple competing carriers with frequent departures, which is why both hubs feel heavily banked rather than sparse.
What changed at Taoyuan in 2026 that affects connections?
Terminal 3’s new North Concourse entered service in late 2025 while the full Terminal 3 project remained incomplete, so some transfer paths improved even as the airport stayed in transition.
Why does Hong Kong feel easier on paper but not always in practice?
A flat 60-minute floor is simple to remember, but real comfort depends on terminal flow, security re-screening and whether the itinerary sits on one ticket. A legal minimum is not a relaxed transfer.
