I do wonder whether Chinese Airlines will be stricter with Skiplagging in the future. Given the fact that e.g. the Czech Online Travel Agency kiwi.com is using skiplagging (besides screenscraping) on a regular basis to be able to offer cheaper flights than the competition.

If one flies with the Airlines regularly and skips a leg every once in a while, ok, but if someone already skips a leg on the first flight with Air China etc. I wonder at which point in time they will cancel the next reservation and/or deny boarding.

The price difference on international o/w flights is huge.

On the other hand side will all the codeshare agreements one can simply book with the codeshare partner for a few EUR more.
