Hi wanted to update everyone on my experience at TPE today with airside transfer with baggage across two PNRs.

Airside transfer WITH baggage is very much alive and well. Time taken probably around 20-30mins.

So I came in on CX and had to transfer onto MH. I had 4 hours to spare and rocked up to the transfer desk (transfer desk A for MH - it's actually China Airlines who is handling agent). Gave them my incoming baggage tags and MH itinerary and they arranged new boarding passes and for bags to be retagged. Given the MH counters were not open yet I only received my boarding passes but they did say bagage tags would be given to me at the gate.

Ended up going into Taipei to buy Chia - De and almost not making it back for the MH departure! Lol. Incidentally also saw my bags sitting at the China Airlines office near the baggage carousels.

but this is just a data point - suppose what's not tested is what's the min time they would allow to take advantage of this service. Still sucks that OW and CX have stopped interlining across separate PNRs...
