Latest change has CI to TPE doing its usual seasonal frequency reductions over the winter scheds.
Daily through 26 Oct
6 weekly from 26 Oct - 26 Jan
5 weekly from 26 Jan - 27 Mar
Also, no 744s in the cards this winter. However, frequencies last winter dropped to 5 for the whole winter period from late October.
This route will most likely become a 359 route once CI takes delivery of them starting in 2016... I would expect YVR to come online in 2017.

Overall capacity to TPE for the winter will still be about the same as Eva Air has added an additional weekly 744 year-round to 4 from 3 in previous years. When CI reduces to 5 weekly over the Feb/Mar period, BR will have more capacity than CI for the first time.
