Tokyo Skyliner return ticket

Question

Keisei offers online discount tickets for non-japanese citizens.

I will be visiting Tokyo landing at NRT, so a return ticket seems to make sense.

However, I cannot find any info about the "return" part of the ticket. The online purchase system only has one "date of trip" field. You have to exchange you e-ticket for a real ticket at the airport.

Does that mean I have to choose a date/time for the return part at the desk on the arrival date? What if I miss the train on the departure date, can I board the next one?

Answer 1

As the order page says,

If you are purchasing a round-trip ticket, we will give you a Ticket Exchange Voucher for the ticket of your return trip at Keisei Electric Railway Exchange Locations.

The "date of trip" field refers to the beginning of your trip.

I assume that the voucher in question is not going to have a date printed on it (since it doesn't say otherwise), and that you rather go to a Keisei station on the day you're leaving and exchange it for a ticket right before going to the platform.
