This thread is a continuation of the hugely popular BA Tier Point runs 2023 thread. This is intended to be a starting point for finding key origin and destinations to tailor your tier point runs, but you will still need to do some leg work to find the correct dates and flights. Also, don't forget that with some of these fares there will be positioning and other costs associated to get to the start of the tier point run.

Other FT threads/boards to watch & external sites
The TP run thread is often a place where good fares are posted aimed at good TP earning. However, it isn’t the only place on FT where such fares are discussed. Here are some other threads/boards you may wish to subscribe to which all relate to good fares.

Premium Fare Deals (J and F) - 2020
Premium Fare Deals (J and F) – 2019 (now closed)

One other invaluable website is Expert Flyer. You can subscribe to the site relatively cheaply and the amount of useful information on there (MCTs, flight loads, fare rules etc.) which will certainly be very helpful if you are regularly looking at booking trips and maximising TPs.
