Flight from Taipei City to Ontario

ThomasFlew with STARLUX Airlines-Jul 2026

Make sure if you pay for a upgraded seat make sure it is the same in the plane as on the website.

SatitFlew with China Airlines-Mar 2026

I noticed several babies and small children crying due to the change in pressure during take off and landing. It causes pain in the their ears, the same way with adults, but they don't know what's going on or how to relieve it. The small children can open their mouth wide and close it, like they are chewing something. For the babies, the parents can push their chin down to open their mouth and let them close it. Repeat until cabin pressure stabilizes. It's much more useful than trying to ask to children to stop crying.
