I am puzzled! I have been looking at ET prices for LHR - FRA in a couple of weeks and the prices have been all over the place!

OK I am used to prices increasing as one gets nearer departure date and depending on the popularity of the flight but ba.com has been doing stupid things.

A week back a return was £67/£67. Then 5 days later it went to £192/£118, then yesterday it went to £111/£111 (for all flights irrespective of time) and today it is £119/£197.

Anybody got any insight?
