The A350 Replaces The Airbus A340-300 on Flight LX122 to Seoul
From an airline's perspective the summer season is just around the corner. It's time to plan and reveal which aircraft will be operating routes. Among routes changing aircraft in the upcoming summer 2026 season is LX122 from Zurich to Seoul.
The flight is a seasonal one, and will be present in the Swiss schedule for the third consecutive year. However, this year the older Airbus A340-300s will be replaced by the A350-900s, the latest addition to the Swiss fleet.
The route will commence service for 2026 on March 29th, retaining the same 3x weekly frequency as prior two years. Flights will operate every: Tuesday, Friday and Sunday.
| Flight Number | Departure Airport | Airport Code | Departure Time | Arrival Airport | Airport Code | Arrival Time | |
|---|---|---|---|---|---|---|---|
 | LX122 | Zurich | ZRH | 13:20 | Seoul | ICN | 07:30+1 |
| LX123 | Seoul | ICN | 09:30 | Zurich | ZRH | 15:40 |
We still don't know if it'll be Swiss' special livery Wanderlust A350 (HB-IFA) or its second classic livery aircraft (HB-IFB) to operate the flight. The latter aircraft is in the process of being delivered these days to the airline. Despite their different exterior appearance, the planes are identical inside.
The Swiss A350 a Major Upgrade for Passengers
This is a major upgrade from a passenger's standpoint. The Airbus A340-300s are among the oldest planes in the Swiss long-haul fleet. Purchasing a ticket, particularly for business class, and flying on the A340-300 can be somewhat disappointing.
The A350-900 on the other hand comes with the latest version of Swiss' cabin interiors. A modern 1-2-1 business class setup replaces the outdated Thompson Vantage staggered configuration alternating 1-2-1 and 2-2-1 layout. Getting a good seat isn't down to luck anymore.
Economy Class passengers can expect a better experience too. The A350 cabin is roomier and with more humidity in the air allowing to breathe better and mitigate effects of jet lag. Seats also get an upgrade with new improved IFE screens.
The A350 Will Unlock Major Savings For Swiss on Zurich to Seoul Flight
Lastly, this is a major upgrade for the airline too. Replacing the A340-300 with the A350-900 on one of its longest routes will unlock huge fuel savings for Swiss on every single sector.
This is significant not only for the environmental impact, but also for (and most importantly from Swiss' point of view) the airline's profits.
Due to the Russian air space closure, far east destinations have become among the longest for European operators. Costs have inflated due to the increased amount of fuel burnt and having a fuel efficient plane such as the A350 on the route will mitigate this.
