I wouldn’t initiate or invite, but if I just happen to be in the same room with myself it would be fine. It would be mostly quiet and we do our own thing, or the occasional silly philosophical or metaphorical discussions but probably nothing real or deep. Or maybe it’ll be a free therapy session, having 2 brains figure out my emotions
I think so because most of the time I need at least a carry-on on top of my personal item. Most budget airlines wouldn’t include carry-on, at least where I am. I’m also doing a light credit card churn for an airline points so at this point I won’t be saving that much going on a budget airline vs just using my points. You get better seats and better service.
Also had one bad experience on a budget airline that canceled and rescheduled a flight so many times that my husband and I lost 28 hours of our long weekend trip. Not worth the time wasted in my opinion.
