We are looking to travel to California next school summer holidays (end July 2015) either:
LHR - SFO return or
LHR - SFO Las Vegas - LHR
The SFO flights are around £960 with Vegas just over £1100.
If I book these as soon as the flights are released at the end of August, what sort of price am I likely to pay or would I be better off waiting for a sale?
Ideally we would like to fly direct with no stopovers.
