I like the idea, it would certainly make long distance travel more fleshed out.
To stay interesting long-term there need to be a random factor included. Example: Klepto sims grabbing your bags before you can claim them back or another family mistaking your baggage for theirs. Maybe even the weapons scanner malfunctioning and your sim getting taken aside by the police.
If the waiting lounge sold postcards that aren't available elsewhere (or the more rare ones of the hamster and bg collection) that would be an added incentive to use the extended travel system.
