Seat reservation for train to airport

[inasham]

I have purchased a Saver Day Pass for train from Zermatt to Geneva Airport on 17 March but it doesnt allow seat reservation for the 7.15am train, and the occupancy rate is labelled as "crazy". So should I be worried that the train might be full and that I wont be able to get a seat? Is there any other way to get a guaranteed seat on the train as I am catching a flight back to Malaysia on that day. Thank you for yoir help.

Hello @inasham 

Seat reservations are only possible on EC and IC trains, not on IR trains.

The train is running during rush hour; however, there will be enough seats available for one person. The train gets crowded from Martigny onwards.

Best regards,
