when I'm in Plalermo next month (Fri 25th to Tue 29th October) I will probably use the Prestia e Comandè bus service for airport connections, as I seem to understand from previous posts that their service is reliable and recommended above the train.
I have seen from their website that it is possible to buy return tickets online, with a small discount and with the possibility to have a pre-booked seat on the chosen rides.
Is my understanding correct that the ticket is in any case valid for the chosen day, so I can take a different bus, i.e. either an earlier one (if I am earlier than expected) or a later one, but (of course) with no reserved seats?
Can I be reasonably confident that if I wish take a bus with no seat reservation there will be no problem in getting a seat, or is it common that buses are full and you have to wait for the following one?
