Can I book a UA connecting flight with Avios?
On the Avios website, I can easily book DUB-SFO, but I want to continue on to Sacramento (SMF) with United. If I search DUB-SMF, nothing is ever available on any day. Can I not book a connecting UA flight on the Avios website? If I go to Mileage Plus, it does offer me the same Aer Lingus flight to SFO with a UA connection to SMF, so it clearly is available on multiple days. What’s going on? Thanks.
