I am looking for flight from LON to LAS ...
I am getting prices at around £750 rtn from LON
However if I book flights DUB TO LAS I'm getting
Prices of around £410 via LON with British Airways
So my question is can I book this ticket but just turn up
At LGW/LHR and check-in for a direct flight to LAS with BA
And the same on the RTN just don't get my connecting flight to DUB
Asking for my bag not to be interlined ...
