Travel Times?
Oh, my.
none at all... of course, it does depend on how good a ship actually is - those with lots of thrust and good sensors can travel faster in hyperspace, since they have more of "safety margain" as they'll have dangerous stuff on their screen sooner, and their bigger engines let's 'em evade even at higher speeds.
But people have been trying to make sense of it all, so far without any success.
I hope some day Mongoose will bring out a Really good BIG Map, with some sort of "rating" for the jump routes. (Say, this route from Immolan to Ragesh is rated 12, so an slow ship with a hyperspace speed of "0.5 per hour" needs 24 hours, while a faster ship with, say, "1 per hour" can make it in 12 hours, a fast ship with "1.5" can get there in 8 hours and a really, Really fast ship with "2.5 per hour" will be there in less then 5 hours...)
Meanwhile GM judement rules.
You could for example assume travel times around 12 hours per major jump route, 18 for a minor and 24 for a restricted one, and then modify that for ship speed - these figures are for a standard warship, a WhiteStar or Courier makes in in half the time, a Battleship or Passenger Liner needs twice that, and Really slow hogs like an Ore Barge or an Explorer might even need triple that time. Then check your travel times, and if your players spend too much time flying through hyperspace for your liking, change your estimations.
