Christmas & bank holidays
These dates are not the usual timetable for the day they fall on. They come from the operator’s published data, which for Christmas and New Year is often late or incomplete, so check with Stagecoach South Wales before you travel. Everything above is an ordinary week.
Not published yet: Christmas Eve, Christmas Day, Boxing Day, 28 December, New Year's Eve and New Year's Day. Operators often publish festive timetables only a few weeks ahead, so check again nearer the date.
