If it is true then^^^, people carry too much/too big/for the interiors of most aircraft ! On 2 flights last week on UA, they gate checked all pax carry-on with #4 written on their boarding cards!

I flew an E90 YEG->YVR last week in J. There are actually only two o/h bins in the J section large enough for rollaboards, and 9 seats. I boarded early to make sure I got room, only to be told by the Dragon Lady that I couldn't put the rollaboard up top. This is Business Class, for God's sake! We argued and I compromised by putting the laptop under the seat. Then a SE arrived next to me, and after getting the same treatment told her to stuff it. She backed off.

At least one FA needs to be sent for re-education.

I will be traveling on a coach reward ticket. It sounds the storage bin is the area where coach has advantage over first class. Are there bins above both sides of seats?

Yes

Thank you all for the information provided.

Yes, but the bins on the port side are much smaller than normal. Big enough for a medium-sized women's handbag or a light coat, but not much more.

In the J cabin...the poster was referring to Y.

wait, what? Y cabin has bigger overhead bins on the E90 than J!?!?!?!

AC should definitely do something about that!!

Absolutely - they just need to add enough floor lighting so that pax can crawl to their seats. The bins are smaller b/c the aisle is off-centre.

Bins on both side are the same size, and standard size rollaboards (14x20x9) can be stowed fore-and-aft in Y. In J, the same bags can be stowed wheels-in or handles-in over the right hand pairs of seats as the bins are deeper.

Here is a couple pictures of UA's Embraer 170, but should be very similar to Air Canada's E190. Notice the first row of coach, where the guy is exposed to the aisle, the bins over him on both sides are the same starting at that point, and can pretty easily take a rollaboard in the north-south orientation.

A bit hard to see, but the front cabin's overhead on the right side is significantly deeper, and can swallow a rollaboard probably as easily as an A320:

The front cabin bins on the left are probably even smaller then those on other regional jets, primarily good for jackets, purses, backpacks, ...etc.

My rough back of the envelop calculation seem to show that on a completely full E190, 65-70% of the passengers can find space for one rollaboard overhead per person.

I take it that the storage bin is the same size on E75 vs E90, in Y?

Correct. E75/E90 are the same design, just a different length.
