I will be traveling from Zermatt to St. Moritz on the Glacier Express 2.10.25, and then by SBB rail early morning 3.10.25 to Zurich Airport. It will be too late upon arrival in St. Moritz to send luggage to the airport. Is it possible to check luggage not needed for the St. Moritz excursion 2.10.25 from Zermatt to Zurich Airport? I will be traveling SBB rail from St. Moritz to get to Zurich Airport 3.10.25, but I am uncertain if this violates protocol.
Any insight/instruction will be appreciated!
