Thanks Rudi. I'm looking at the following routings.
27-Nov CX 0271 AMS 0730 MAN 0750
27-Nov BA 1389 MAN 0930 LHR 1030
100 minutes for the connection. CX gets into Terminal 2. BA departs from Terminal 1.
And possibly this.
29-Nov BA xxxx LHR 0745 MAN 0840
29-Nov CX 0270 MAN 1000 AMS 1220
80 minutes. Think this is cutting too close? I could take a flight up to Manchester the night before. But prefer to spend the night in London.
