I can't find a lot of seat reviews for the A220-300. I'll be flying ATL-BUR on the 223 in July and I'd rather not get stuck in a squished seat for a 4.5-hour flight. Finding reviews of the seats on the 223 has been harder than you'd think.

Seatguru only has data on the 221, and Seatmaestro doesn't even list any of the 220s. Seatmaps.com seems to indicate that 18A/E (exit rows) are good, with no seats in front of them, but says that 18B strangely has no underseat storage despite there being a seat 17B. I'm 6'-3" and left-handed, so I am all about seat 18A, and Mrs. LeavyScreens could get the 18B aisle. What's the intel on these two seats?

Also, are there any C+ or F seats that are good or crappy? I'm not sure that I'm willing to trade ~65 inches of pitch for C+, but if the stars align and our RUCs work I can go with F.
