yeah £9 each way or £15 return.
Does the £21 travelcard include tube etc? I normally just use my Oyter card when in London but the travelcard option works out the same (at worst).
Yeah, £21 includes the travelcard, but might be better just using your Oyster card once you get into London. Dunno.
Maybe the OP is not completely bonkers. The tube journey is 55 mins and while that may be no fun, it’s more reliable than sitting in traffic?
It could well be a better plan, but it just depends on the traffic around the M4 as it approaches the M25, the traffic on the M25 and the traffic on the A40 to get to Hillingdon/Ickenham.
On a workday morning, I would be guessing it would be pretty terrible, even if leaving early.
Denham might not be a bad shout…
