Scenario: I got an offer from the program I want to attend two days ago. However, I had scheduled two other interviews in case I didn't get an offer from my top pick. The other interviews already booked airfare for me. I get charged for the plane tickets if I cancel my interview. Do I still attend the interviews just to check the other programs out if I am set? I also really don't want to pay for the air fare. Any tips or words of wisdom?

If I have an offer for a PhD program from a top 50 school in a awesome location and a top 10 school in a less ideal location, am I crazy to choose the lower ranked program for the location?

I have applied to 11 biosciencey PhD programs at a decent range of quality of schools. My reach schools were WashU, UWisconsin (3 programs here) and UMichigan. My "safety/mid range" schools were Utah, Oregon Health and Science (2 programs here), Oregon, Cincinnati, Montana and Montana State. So far I have heard back from around half and the only two interviews I have gotten have been with "reach" programs. I have an interview with Wisconsin and Michigan. I have gotten rejected from Utah, Oregon, one program at Oregon Health and Science and WashU. What is even crazier to me is that I just did an REU at Utah with the same program I applied to. My GRE and GPA were all either at or higher than their average accepted applicant pool. The PI I had wrote a good enough letter to get me interviews with Wisconsin and Michigan so I feel like he liked me enough. Anyone have any insight on what could be happening? It doesn't make any sense to me.
