I will be staying in Ealing for rest of the trip and can easily get car service from the hotel for my 10:30 flight.
Thanks for the tips. I'm becoming unsure about the walk especially as I will be slow given a back condition I have.
My husband is urging me to consider car service but if I reserve in advance and there is a long line at immigration making me late for the window car service operators provide, I'll be charged for that. Black taxis are a rip off so I avoid them at all costs.
Since LHR T3 does have free wifi, is it possible to go online to request car service once I'm landslide? Will they come within 10-15 minutes? If so, any recommendations for an inexpensive and reliable car service? Thanks.
