DEAR TRAVEL TROUBLESHOOTER: I recently tried to use my Chase points to book an airline ticket on Aeromexico. After seeing and confirming the availability of an award flight on its partner airline, Virgin Atlantic, I made two transfers of 37,000 Chase points to Virgin Atlantic to book the flight. When I went to click “purchase,” I received an error message and could not complete the booking.

I called Virgin, which said that Aeromexico had not released the flight to them, and there was no button they could push to book the flight, despite it being advertised in multiple locations, including their website.
