hey there
two comments:
- DO. AVOID. FRA. Munich is a paradise comparing to what can happen in Frankfurt. Just don't do that.
- Wroclaw - London: why don't you take a direct flight with LCC WizzAir? Buy "priority boarding", "extra legroom", "checked-in luggage" option and you will be better off than any LOT/SAS/LH. Easy train from London Luton to the city center (St Pancras I think). I just did WizzAir Luton->Katowice (South of PL) and I'm seriously considering ditching *A on London route entirely.
