If you want door-to-door then a taxi is your only option but if you
are prepared and able to travel by rail it is competitive time and
price-wise. You can take the rail-to-air link from the terminal to
Luton Airport Parkway station where you have four trains an hour to
West Hampstead Thameslink either direct or same-platform change at St
Albans. From WHT it's a 100 metre walk turning right along West End
Lane to West Hampstead London Overground station. From there services
run every fifteen minutes to Gunnersbury, two minutes walk from
Chiswick High Road. The minimum time I've done this journey in is
just over one hour - typically it should take you an hour and a half
and cost about twenty-five quid for two adults. I live locally and
our local cab company charges about £70 to Luton Airport for a journey
that takes a similar time. Assuming that you have no problems with
mobility, it's not a bad journey by rail unless your bags are really
heavy.
