Its great, was only my second time on B6. I usually have points so splurge on a lay-flat but was super happy considering the price I couldn't resist paying cash for an economy ticket. Plane both ways was maybe 2/3 full. For a taller person the legroom was generous, way back I didnt have anyone in front of me so didnt have to worry about anyone reclining in my face. Food was pretty good as well and nice to not get a greasy microwaved pasta like I was expecting. Plane on my way out was only delivered 2 weeks ago so was quite "fresh" as well

TBH I am not a huge fan of the preclearance at DUB, not a lot of places to go once you clear immigration but not really a B6 issue
