I can see things both ways.
We're in Eugene, and if people are coming from the East coast, they might land at 11:00pm or midnight. Usually UBER time if its that late.
Also if people have been on a plane for 7-9 hours, they might prefer to travel in casual clothes rather than their job market attire. At the same time, when I interviewed at UO, they asked if I preferred to go sleep (it was 8pm when I landed and I was on east coast time) or join folks to play darts and enjoy local pub food. I opted for the latter and it was a great to get know people in a more chill scenario.
So I see tradeoffs, but in most settings we offer to pick them up, but we're flexible and things can be situation specific. It's only awkward when someone books a flight to visit us that goes through Portland because either didn't know what city our university was in, or they assumed it was so small there would be no airport (the MSA has 250,000 so there about 10 different connecting flights with all the major airlines even though we aren't a hub for anybody).
