That does sound easy Orca - any idea on whether you need to book before, etc?
Have narrowed down options for flying now (by eliminating Lufthansa due to extortinate bike charges and tales of woe from others) to the following:
1. Fly Easyjet from either Gatwick or Stansted. Both flights out on the Wed are very early (would get in to Munich at either 9ish or 11ish) and both flights back on the Tues are very late (get back to UK around 11pm) - still more time to get over hangover. Price is about £80-£110 (Stansted cheaper) plus 20 quid for bag and around £40 for bike. Throwing in £10 to pay on credit card gives overall price of around £150-£180.
2. Fly BA from Heathrow. Flights are at more sociable times (going out they get into Munich a little later than EJ and coming back leave in the afternoon). Price is around £130 to £150 (including 1 bag) but bike charges look like they could be around £80 (am confirming this with BA as website suggests might be more like £60). So overall cost is likely to be north of £200 - around £210 to £250. Plus there is the small matter of possible strikes by cabin crew to gamble on.
Am leaning toward EJ now. A little cheaper, easier airports to get to for me and no risk of strikes are all pointing that way. No idea if any of this is useful for others travelling from down Sarf but helped me get the choices clear in my head anyway!
