I was in row 4 and 5 middle seats in the A350 suites last July SEA-NRT and back on the way to & from SGN via Vietnam Airlines (which also was missing the graspers in their center seats in business class). I took my trusty usb mini fan and used it a few times on the flights and it worked great. I’m always way more uncomfortable with heat than everyone else, btw, and still this little fan was all I needed. VersionTECH. Mini Handheld Fan, USB Desk Fan, Small Personal Portable Table Fan with USB Rechargeable Battery Operated Cooling Folding Electric Fan for Travel Office Room Household Black . It got even more use in Vietnam’s terrible July weather.
