Remember that the place he's going is several miles into the second zone. This will put the fair up
He is going to "Aleja Dzieci Polskich 20, 00-999" it is almost a straight road from the airport, at 2pm he will miss rush hour. There has been a lot of new roads built around Anin/Wesola & Wawer, so the travel time is reduced.
I do not understand why you guys have / had an issue with the airport taxis in Okęcie
I don't have an issue, I always take a taxi from the airport rank, mostly I also try to take MPT or Eko taxi. The difference is I speak Polish and I know Warsaw road network very well, so no-one will be taking me for a ride.
