hello , i would like to book a train , leaving cambridge and going to stansted airport . i just want to arrive in stansted airport on tuesday before 11:00 .
ok , when would you like to leave and what time would you like to leave at ?
{'service': 'train', 'act': 'inform', 'slot_name': 'arrive', 'value': '07:08'} {'service': 'train', 'act': 'inform', 'slot_name': 'leave', 'value': '06:40'} {'service': 'train', 'act': 'inform', 'slot_name': 'depart', 'value': 'cambridge'} {'service': 'train', 'act': 'inform', 'slot_name': 'dest', 'value': 'the airport'} {'service': 'train', 'act': 'inform', 'slot_name': 'id', 'value': 'tr1951'}
tr1951 leaves cambridge at 06:40 and arrives at the airport at 07:08 . would that work ?
