I'm travelling from Los Angeles to Manchester and debating on whether to take dual flights, so a main flight from LAX to LHR then a layover until the flight from LHR to MAN. Or to take just the flight from LAX to LHR then get a train to get to MAN. The train is an hour or two more travel time, but there's more flexibility in my departure time and I don't have to worry about going through TSA/security, etc. Prices are a bit cheaper for train, but that varies. Any feedback/recommendations???
