The practical part
Here’s how to get there.
Allow for a specific 343 departure
The current working-day table shows four passages in each airport-to-airport direction, so it is not a turn-up-and-go shuttle.

Board for the other airport code
At TFN take the service shown for Aeropuerto Sur TFS from the bus stop on floor -1; at TFS take the service shown for Aeropuerto Norte TFN from the stop on floor 0, arrivals. Those are the stop locations Aena lists for each airport.

Use the direct airport segment
Aena describes only the TFN–TFS section as direct and non-stop. The full 343 route also includes Puerto de la Cruz and Estación Costa Adeje.

Direct airport segment
Aena describes the TFN–TFS airport segment of line 343 as direct and non-stop, taking about 50 minutes. That description applies to the airport-to-airport segment, not the whole route between Puerto de la Cruz and Estación Costa Adeje.

Limited departures
The current timetable has separate working-day and weekend/holiday tables. On working days it shows four passages at each airport in the TFN–TFS direction, so plan a fallback if your flight is delayed.

How often does the airport-to-airport bus run?
Not often: the working-day table shows four passages in each direction, with a separate weekend-and-holiday table. It is not a turn-up-and-go shuttle, so plan around one published departure and a fallback if your flight is delayed.

The other half of the plan
And the way back.
Do not treat 343 as a turn-up-and-go shuttle: recheck its limited timetable for the opposite direction and leave time for terminal, baggage and flight procedures at Tenerife South Airport (TFS) or Tenerife North Airport (TFN).
