Hello AkarpLink opens in new window.
You are correct in your understanding. The airport luggage transfer option allows you to drop off your luggage at specific stations, such as Lausanne, and pick it up at the SBB counter in Zurich airport the next day. However, this service does not allow for the transport of bikes. On the other hand, the station-to-station SBB luggage transfer service allows you to drop off your luggage, including bikes, at many more stations, including Renens, and pick it up at the SBB counter in Zurich airport. This service takes 2 days and costs 12 CHF per bag and 20 CHF for bikes. The main difference between the two services is the availability of bike transportation and the cost per bag. The transfer time is the same for both services. Please note that the station-to-station service is more suitable for your needs as it allows for the transportation of bikes and is more cost-effective for luggage transfer. I wish you an excellent weekend. Kind regards
