I am planning a holiday from the UK to USA for May 2014. We (2 adults) will fly from Heathrow to Honolulu. Two weeks later we will fly from Honolulu to Las Vegas. After a road-trip we will fly from Las Vegas back to London Heathrow.
Advice would be much appreciated on how we might obtain the most economical combination of international/ internal flights; which airline(s) to use etc.I appreciate this question may be very general. We have flown to the USA before, but have yet to use domestic U.S. airlines.
