Hilton HHonors - AMEX Surpass and Empire CLS

One of the sign up bonuses for the surpass card was a $50 credit on your first Empire CLS car booking. I'm thinking of using this for airport transfer on my upcoming honeymoon and wanted to see if anyone here has tried it and has any additional information/thoughts?

I would be using it in BKK, but am interested to hear experiences from any location they offer.

I checked their rate for JFK-Manhattan and it was almost double the normal rate I pay. I suggest checking their rate against the hotel airport limo rate for BKK.

Tried twice to book using the 50.00 credit. Still significantly more than others available. Make sure you check other limo services.
