Assign trip members/guests to specific reservations (flights, hotels, etc.)

[ByteBolt556]

Problem

Reservations (flights, accommodations, restaurants — whether added manually, imported via AirTrail, or pulled in through the AI/KDE Itinerary booking parser) are currently modeled purely at the trip level: dates, times, confirmation number, notes, status, files. There's no field indicating which trip member or guest a given booking actually belongs to.

Two concrete cases where this becomes a real problem:

Case 1 — different people, different bookings, same trip.
I'm planning a trip with my parents. When I import their flight, it lands as a reservation with no way to mark that it's their seat, not mine. If I'm flying separately, I end up with two nearly-identical reservation cards and nothing but manual title-editing to tell them apart.

Case 2 — split accommodations, same trip.
On a trip with my wife and another couple, we don't share every hotel room or every night. Some nights it's the two of us in one place, the other couple somewhere else, or the room configuration differs. There's currently no way to indicate who a given accommodation reservation actually covers.

Both cases come up constantly for group and family trips, and right now the only workaround is stuffing a name into the title or notes field by hand and hoping it stays consistent.

Suggested Solution

Add an optional member/guest assignment to reservations — the same pattern that already exists elsewhere in TREK:

• Budget items already support an optional userIds array (create_budget_item / create_budget_item_with_members) to say who's splitting a cost.
• Packing list items already support member assignment.

Reservations (and accommodations, and transport bookings) don't have an equivalent. Concretely, I'd suggest:

• An optional travelerIds (or similarly named) field on reservations/accommodations/transport bookings, accepting one or more trip members and/or named guests.
• Surface this as a small avatar/name badge on the reservation card — similar visual treatment to how budget splits are shown.
• Optionally, extend the existing type-filter pills in the Reservations panel to also filter by traveler.

Additional Context

This would also make the AirTrail two-way sync noticeably more useful for group trips — right now an imported flight has no structured way to indicate whose itinerary it came from, beyond the confirmation number.

Since userIds-style member assignment already exists for budget items, this wouldn't be introducing a new pattern to the codebase — more extending an existing one (member/guest tagging) to a second feature area (reservations) that currently lacks it.

Add from #1557 as requested.

Allow filtering of view to only those bookings, transportations, places, etc assigned to self (or to certain individuals)

I opened a similar request earlier, but it got closed in favor of this thread, so I’ll post my use case here.

We’re currently planning a trip to Japan with 8 people who live all over the world. Everyone is booking their own flights (we don’t even arrive on the same day). Right now the only way to distinguish whose booking is whose is to put the name in the title (e.g. “John arriving from Mexico”). This has the side effect that TREK thinks the person visited Mexico, even though they never did.

It would be really helpful if we could:

Assign bookings / flights / transport to specific travelers (or to everyone)
See a clear visual indication in the overview of whose booking it is

On the packing list side: the list is currently fully shared. It would be nice if one person could create a basic packing list and then send/copy it to everyone so each person has their own version to check off.

For tasks it would also be useful to assign people more flexibly — for example assign “Apply for visa” to everyone, or assign only John to “Book tickets for the digital art museum”.

TREK is already an amazing piece of software, it just doesn’t feel fully designed around groups where everyone has their own individual bookings and tasks.

This is the feature that would let me finally move to TREK.

Done — shipping in 4.0.0 🎉
You'll be able to assign trip members and guests to bookings and transport, see who a reservation is for right on the card, and filter the reservation list by traveler.

That's great news! Looking forward to moving all my tripit data.
