I hope all of you and your loved ones are coping during this trying time. Whether you're hunkering down at home with work or study, or are still needed in public as a healthcare professional or otherwise essential employee, I wish you all good health and peace of mind.

Below I will go into detail on the current policies for the top five US airlines (defined by passengers carried).

I recently booked myself in United economy to fly back to the United States from Buenos Aires for Christmas. Why would I torture myself in economy? Well, a few reasons...

It's the holidays. Holidays = not much premium cabin award space, and economy cash tickets are pricey.
There aren't too many Business Class product options between Buenos Aires and the United States, and the one that has the most award space tends to be United. United's Business Class is OK, but nothing to write home about. Sometimes I don't feel like using more miles for it.
