Mileage running now is silly. We’ve no clue what status requirements will be for 2021 (some hotels and airlines are already granting extensions), so it could easily be a total waste of $$.
Bars, restaurants, and major tourist attractions are all closing. Sure, you can take a leisure trip...But would it really be fun?
Non-essential Business travel is already suspended by most companies.
Who does that leave? People who absolutely must fly — to get home, to perform essential business, for a family emergency, to care for a loved one, etc.
In light of that, I think the low fares are nice.
The true meaning of mileage run is not leaving the airport, just turn back. Bars, restaurant and attractions are irrelevant.
