Flight was normal, food typical , good overhead storage space. Worse part was the Lisbon airport. Multiple checkpoints. Departure gate not listed till 90mins. prior to departure. Then surprised with extremely long lines at final checkpoint. Took 90 mins to get through final line then 1/2 mile run to departure gate. Fortunately plane was held. 45mins late takeoff. All due to under staffed checkpoints. Advice -don't stop to enjoy that last glass of Port, get to your departure gate ASAP.
