The other night, my wife and I boarded a United CRJ-700 carrying full-size rollaboard suitcases. We have been flying a lot of mainline lately and forgot that the CRJ-700 overhead bins do not quite fit a complaint-but-full-size domestic carry on.

Luckily we were in seats 7CD. Seats 7CD on the CRJ-700 are magical, arguably better than First. Those two seats -- and, as far as I can tell, *none other* -- have enough underseat storage space of the correct size to fit two full-size rollaboard suitcases.

This is kind of magical; this is in fact better than the underseat storage size on many mainline aircraft. (We have stowed a rollaboard underseat in, say, an SQ A380 or 77W F seat before , but that's a little different.) This is almost as magical as the two special seats on the Micronesia 737 that have the legrests (which we have taken once or twice NRT-ICN and which was a fun little FlyerTalk secret).

Here's to you, 7CD. Never change.

(I'm just posting this now because I am flying another CRJ-700 and saw a pax board with a big rollaboard then explain to the FA that he is in seat 7C and he thinks it will be a-okay. She agreed to let him try it.)
