Rosalia's Boyfriend Wouldn't Take Her to the Airport

Rosalia booked a trip to visit her family and when she was planning it her boyfriend offered her a ride to the airport so she wouldn't have to use rideshare.

Fast forward to the days leading up to the trip and he hasn't confirmed anything with her and she ends up taking an Uber and now she wants to know if this is a red flag.

Simon helps her out but what do you think, should she have been more confident and direct by asking him to take her instead of waiting for him to remember his casual offer weeks earlier?
