This morning on flight 35 (LGW-IAH) the concierge helped one of the passengers sitting near me with getting a car service reservation to meet him at IAH. Upon arrival, the IAH concierge came on and told him there should be a limo downstairs waiting for him. On the trip over last week, the IAH concierge asked me not only about a shower upon arrival at LGW but if I needed assistance with ground transportation after landing. After I said yes to the shower and no to transportation, she asked if there was anything else she could assist me with for my arrival in London the next morning. So they can do more than just smile and reserve a shower at the arrivals lounge.
