We are pretty infrequent flyers and not that savvy, so tend to book directly through an airline. We did do a package through Costco a few years back that worked out well. On recent trips to London and Scotland, we traveled British Airways premium economy. I'm 6'2' and a knee replacement, so I beg for all the leg space I can get. We have been happy with BA, and typically it is a 787 or on occasion an A380 aircraft out of Chicago O'Hare. Comfort has been fine and service very good. On a recent trip for DW and DD to UK, they experienced some short notice flight cancellations that caused a panic. DW is deathly scared of flying, so any last minute change to the plans really does not go well. It seems all the airlines are having cancellation issues right now.
