How to approach this..

For a couple weeks now my husband and I knew about my neighbor needing a ride to the airport tomorrow, no biggie ya know we have plenty of room in our truck.. Well today she came over to inform us that she read the times wrong and she needed to be there at 5am and she filled her car up with gas.. She don't have a big enough car to fit all of us.. Well anywho I kinda find this odd because before hand she would seem to only wanna talk to my husband or come outside in the backyard when my husband was taking out the dog (she has a dog too she takes hers out when he is out, that or I'm just missing something) I have tried to have a conversations with her many times before but she seemed uninterested. Anywho she pretty much expects my husband to be taking her to the airport.. I do not like this idea at all, it just seems way to fishy.. I do trust my husband.. He isn't the issue.. Its her I'm having a weird feeling about. So how would any of yall approach this situation? Or I'm I just being silly??
