China Airlines has filed a one-time aircraft change on its Taipei Taoyuan to Prague route, swapping the Airbus A350-900 that normally operates the service for a larger Boeing 777-300ER on two dates in late October 2026.
According to schedule filings reported by AeroRoutes on August 18, 2026, the SkyTeam member has listed the 777-300ER on the outbound leg on October 29 and the return on October 30. The rest of the season remains scheduled with the A350-900.
The filed timings
The affected rotations are CI067, departing Taipei Taoyuan at 23:45 and arriving in Prague at 07:25 the following morning on October 29, and CI068, leaving Prague at 10:30 and arriving back in Taipei at 05:25 the next day on October 30.
One-time equipment changes of this kind are routine in airline scheduling and rarely make headlines, but they are usually a signal of something happening behind the scenes. Carriers file them to cover maintenance rotations, to reposition an airframe, to absorb a delay elsewhere in the network, or simply because demand on a specific pair of dates justifies more seats than the regular aircraft can offer.
Why the 777 is the bigger aircraft here
The substitution is a genuine upgauge. The 777-300ER is the largest twinjet in the China Airlines passenger fleet, a stretched widebody built around two enormous GE90 engines and distinguished visually by its raked wingtips. The A350-900 it replaces on these two dates is a smaller and more modern twin, lighter on fuel and lower in trip cost, which is why it has become the airline's standard tool for thinner long-haul markets.
Prague is one of those markets. China Airlines opened the Taipei to Prague route as its gateway into Central Europe, and the service has been operated with the A350 since launch, an aircraft sized to make a long, seasonal and relatively slim route work commercially.
A brief window of extra capacity
For passengers booked on those two dates, the change means a different cabin product and a different seat map, and any seat selections made against the A350 layout will need to be revisited once the switch is loaded. For spotters in Prague, it means a rare visit by a China Airlines 777-300ER at Vaclav Havel Airport, a type that does not normally appear on the route.
Filings like this can and frequently do change again before departure. Schedules published two months out are working documents, and a one-time equipment note is among the easiest things for an airline to reverse if the underlying reason for it disappears. As of the August 17 filing, however, the 777-300ER is what is loaded for October 29 and 30.
