She asks when she can see you before you leave: what it signals

A question with a deadline attached tells you what she is protecting. She is not asking whether you will ever meet again. She is asking whether this trip gets a second chance before it closes, which means she has noticed the end date and does not want it to pass by default. Look at what came before the message. If she has been asking about your last day, your flight, or a place she wants to try, the question is the next step in something already moving. If she went quiet for a day and then asked out of nowhere, she is probably checking your availability, which still counts as interest but suggests she is being careful about pace.

Your job is to turn an open question into a decision she only has to accept. Name a specific day or evening, or offer two options she can pick from, and tie it to something real like a place you both mentioned or a time you are already free. Confirm in the same message that you want to see her, without making it a speech. People stall when the logistics are unclear, so carry the planning load: suggest where you would go, roughly how long it would take, and what time you need to leave for the airport or your next stop. If your schedule is packed, say so plainly and offer the one slot you can make. Do not make her work through a list of your availability.

Once she has asked, reply within a few hours if you can, because a plan that sits for a day starts to look like a polite no. If she says yes, lock the time and place that day rather than leaving it vague. If she does not respond to your suggestion, wait for the next natural moment in the conversation, then send one short follow-up that offers a different option, such as a shorter meetup or coffee before your flight. If the second message also gets nothing, stop chasing. You have made the offer twice, and a third message turns a travel plan into pressure. Let the trip end without a plan rather than spending your last evening wondering why she went quiet.
