Travel is where most practices quietly end. The mat is at home, the room is strange, the schedule is not yours. The trick is to lower the bar on purpose before you go, so that practising away is not a special effort but the obvious thing.
Twenty minutes, no mat.
A folded towel or blanket is enough. You do not need grip for what you are about to do; you need a clean patch of floor.
Start seated, five minutes of breath to arrive in the new place. Then a few rounds of slow sun salutations to find out what the body feels like today — it will feel different after a flight, and that is information, not a problem. Add a standing pose or two for the legs, a forward fold, a twist done seated. Finish flat on your back for a few minutes.
It will not be your home practice, and it is not meant to be. It is the thread that keeps the practice from snapping while you are away, so there is nothing to restart when you get back.
