We just landed in LIS about an hour ago. We walked right up to the customs agent and through into the food court and up to the TAP lounge. It took about 2 minutes so maybe LIS has their act together or else we were the only plane landing at that time. Plus we were almost first off the plane being in J and on the first bus off the tarmac.
I thought we must have missed something b/c we never went through security unless there is security down the hall where the gates are.
