The SmartBus Route 903 will start on Monday 20 April. Commuters can travel for free for the first two weeks from Monday, 20 April to Sunday, 3 May.
If you're planning to take advantage of the Metlink 5% off deal and only travel by bus along this path (eg existing route 700 or 291), it would be best to avoid validating a large value ticket that overlaps with this promotion.

I pity the poor bus drivers that have to do that entire route and back again all day! +1 for the find though, great bargain.
