Top tips for the "Dim Sum / Chicken adobo" fare:

• At more than 5 weeks after most of us booked this fare it looks increasingly likely that the fare will stick. However prudence is still advisable and we should all avoid contacting the booking agent and if essential to contact try to deal with the airline direct.
• Check that your original itenary is intact and ticketed as PAL revised their LHR flight schedule in early September and there appear to now only be 5 flights a week now rather than daily. Use TripCase to do this - see post #114 on how to do this (thanks to @MyFlights App). If you have incurred an involuntary change you can contact PAL and they will permit one change to amend your itenary. They appear to be flexible to shift flights to adjacent days, but if you try to push to be rerouted on another carrier to maintain the original itenary times you might find your flights are cancelled and you end up with a refund.
• Online seat assignments are not possible on PAL when booked through a 3rd party, you have to call up, it is best to call PAL on 0808 164 9888 rather than the booking agent.
• Whilst it looks like the fare is going to stick be aware that making other travel arrangements around this booking are at your own risk so consider making bookings that are refundable or covered by insurance if needed.

In hopes that this will go ahead, here's a wiki to see who's going and when.
