Tried a few places but none as good as my old local in Manchester. Any recommendations?

Today my 2017 Audi A3 wouldn't start, the dash had a notification "Electrical system: low battery charge". After a jump start it was running and I drove for approximately 45 minutes in an attempt to charge the battery. When I stopped the car, it wouldn't start again and the same fault appeared. I jump started the car and took it to a local garage. They said the battery needed replacing and the alternator did too, it was only reading 12.9V and should be around 14V.

They replaced the battery but not the alternator as the they couldn't get the part until Monday. I then drove home which took about 1.5 hours with no issue. I started the car again once I parked at home and it started. My issue is I need to drive to the airport and back tomorrow, 30 mins each way, I'm wondering if this is likely to be ok or if I shouldn't risk it. I'm picking up an elderly family member. The earliest I can get the alternator fixed is Monday. Any help appreciated, thanks!
