Update: As commenters point out, this pricing is intentional. After booking dozens of BA flights you’d think I’d realize this by now, but if you book at least 2 BA partner airlines on the same ticket then the pricing will be based on the multi-carrier award chart which is completely different than the low per-segment Avios pricing we’re used to.
At any rate, the lesson remains the same, book one-way (or one-segment tickets) if needed to avoid that situation.
Related: The Chase British Airways Visa Signature offers 50,000 Avios for spending $2K. Points are also transferable to BA from Chase UR, AMEX MR, and Starwood.
DDF techie wiz BAHayman asked me why the following round-trip itinerary is pricing out at 90K Avios and frankly I’m stumped:
When booked as 2 one-ways the price is correct at 64,500 Avios total.
Tel Aviv-Berlin is 10K, Berlin-JFK is 20K as it should be:
LGA-Philadelphia is 4.5K and Philadelphia-Tel Aviv is 30K, as it should be:
I was able to replicate this for several dates. Anyone have any idea as to what the BA.com pricing logic might be?
In the meantime as I wrote in the BA knowledgebase (albeit for other reasons), book one-ways when using Avios. Sometimes you’ll even have to book the ticket above as 4 separate tickets to get BA.com to show the flights, but the price will still be 64.5K Avios.
