BT384 TLL RIX 0520 0605 connecting in Riga with OK883 RIX PRG 0815 0900
I have looked at the historical flight information for this connection. There is no info on BT384 but we know from a video extra featuring Sam and Dan that they landed on-time in riga and have a 2 hour connect time there. OK883 left early at 812am and reached Prague at 856am four minutes ahead of schedule.
