Pre-COVID I traveled frequently to see family on the opposite coast, this is still possible with TSA Pre and only carry on bags at most major airports.
However, it's risky now because airlines are under much more pressure to get flights off the gate, and they'll gladly close the door on you if somehow they have a quick boarding process.
Yeah. I’ve gotten to a gate 30 minutes ahead of time because I’ve been in a lounge or just had a connecting flight and basically gotten a cross “Why are you so late?” at the gate.
