Sigh. EVA has gradually been reducing space in Y from 33" and 9 abreast, to 31" and 9 abreast, and finally 31" and 10 abreast.
Let's just hope they don't convert any of the current planes to this configuration. They had one of the most comfortable Y seats of any carrier. I hope this high density configuration is only confined to shorter flights like SEA, YVR, CGK, PVG, BKK, HKG. A 15 hour flight from any non-West Coast city to Taiwan in this seating would be pure torture.
