There are still bargains to be had - Out of Heathrow, Gatwick and Stansted.
Direct to Munich was a bit pricey, so l started looking at other places in Germany (Stuttgart was about 90 pounds) and then Austria (Innsbruck, Salzburg, Vienna) and Switzerland (Basel and Zurich).
The cheapest I have seen today is Stansted to Vienna for 40 pounds.
From Vienna Airport Station you can get a train to Munich with 1 change (in Salzburg).
From Innsbruck; quick bus from the airport to the Hauptbahnhof, then a direct train to Munich (1.5 hours).
And from Zurich Airport Station you can get a train direct to Munich.
The latter is what I have just booked.
Heathrow to Zurich was 60+ pounds, but I paid 80+ pounds with 23KG of hold luggage.
Once again, Zurich Airport to Munich by direct train.
