Reward Flights Pricing Glitch?

Out of curiosity I've been browsing tonight and thought I'd see if I could recreate our cancelled May trip for 2021.

If I price it up in the App or on the Web as two one ways (LHR - IAD and LAS - LHR) the pricing agrees with the "Standard Season" table of 10,000 EC to IAD and 67,500 UC back from LAS.

If I price it up as a multi-trip return however the outbound jumps to 25,000 EC to IAD, and 85,000 UC from LAS This jump happens both on-line and in the App.

Hopefully it's just a glitch but I wonder if anybody else has seen this?

PS - No we wouldn't be flying EC - we have the credit card PE upgrade voucher

Are the higher priced flights definitely direct? If they include DL domestic connections that would push up the price.

Hi Gumshoe

They’re definitely the direct flights - VS21 outbound & VS156 on the return.

Having now taken the taken the app to the booking page It prices correctly at 77,500 miles so definitely a glitch me thinks!
