$50 after walking off a $1200 flight, $60 upgrade to board early, and $12 in cocktails is not a substantial amount. Plus lunch/dinner on the way to/at the airport for $40. And you're gonna pay $8-12 to get downtown via public transit, then make a transfer to a bus and walk two blocks to your hotel. Fifty bucks for a taxi is a lot, but a rounding error on a transatlantic flight/trip, and will drop you off in front of the hotel, might even carry your bags into the lobby for you, or at least load them onto a luggage cart.
