Short answer is yes, longer answer is that it may require a request made through the company at time of booking, as the seats are not displayed as available online. On one of my flights early May, there was a family (two parents + 3yr old) occupying an A, B, C row, but this was prior to middle seats being blocked off, and when flights were departing with very few people on board. Since mid-June, my domestic flights have been full - middle seats notwithstanding.

As for temperature checks, airlines and airports are willingly participating in whatever ruse they can muster to instil some confidence among the fearful and ill-informed. As we learn more about this virus, we're seeing that in excess of 30% of covid-positive people remain asymptomatic, in other words, they don't display a fever and temperature checks would do nothing to prevent them from boarding.

AC staff themselves aren't exactly promoting the reeks-of-desperation #timetotravel theme. I've now seen a few flight attendants walking down aisles in masks, gloves and full-length disposable medical suits. If the CEO is so desperate to encourage people to mingle and travel (against the advice of our medical experts who are actually qualified to make such a decision), perhaps he might consider the impression made by having jauntily-scarved hazmat squads collecting water bottles from his bemused customers.
