Embraer E175 vs CRJ-900 — Which Regional Jet Is Less Miserable?

Regional flying has gotten complicated with all the equipment-swap chaos and last-minute aircraft changes flying around. As someone who’s logged north of 200 flight segments across United Express, Delta Connection, and American Eagle over the past six years, I learned everything there is to know about the difference between boarding an E175 and boarding a CRJ-900. The answer to which one wins? The E175. Not marginally. And if you’ve already made the mistake of ending up wedged into a CRJ without checking the equipment type first — you already know exactly what I’m talking about.

Regional jets exist because airlines need to serve thinner markets without deadheading half-empty mainline aircraft on routes that can’t support them. That’s the operational logic. The passenger experience logic is something else entirely — you’re folding yourself into a pressurized tube roughly the diameter of a municipal bus and trying to convince yourself it’s normal. Both the Bombardier CRJ-900 and the Embraer E175 live in this space, frequently on identical routes, sometimes on the same route on alternating days. The gaps between them are specific and measurable. They matter enormously if you fly more than a handful of times per year.

Cabin Width — The Number That Matters Most

But what is cabin width, really? In essence, it’s the interior measurement from wall to wall at seat-rail level. But it’s much more than that — it’s the number that determines whether you spend 90 minutes touching a cold fuselage wall or whether you actually have room to exist.

Here’s what the tape measure says: the E175 cabin runs approximately 82 inches wide at seat-rail level. The CRJ-900 comes in around 69 inches. That’s over a foot of difference. You feel every single inch of it.

Both aircraft run a 2-2 seating configuration — no middle seats on either plane, which sounds like a fair trade until you’re actually sitting in a CRJ window seat and realize the wall is essentially touching your shoulder without you leaning toward it. On the E175, there’s genuine shoulder room. You can shift positions without bumping your seatmate. Small thing in isolation. Enormous thing across a 90-minute hop from, say, Columbus to LaGuardia.

Frustrated by the constraints of adapting an existing business jet platform, Embraer’s engineers in São José dos Campos designed the E175 from scratch in the late 1990s using a clean-sheet fuselage optimized specifically for passenger use. The CRJ-900, meanwhile, evolved from the original Canadair Regional Jet — which itself grew out of the Challenger 600 business jet, sketched out in the 1970s on a narrower fuselage that was never meant to carry 76 passengers. This new regional configuration took off several years later and eventually evolved into the CRJ series enthusiasts know and debate today. That origin story lives in the fuselage walls every time you fly it.

Window seat passengers on the CRJ-900 also contend with a fuselage curve that physically eats into shoulder space — a consequence of the narrower cross-section. The E175’s cabin shape is more rectangular, which sounds like a minor architectural footnote until you’re on a 6 a.m. departure from Charlotte to Providence and you realize you haven’t once touched the wall.

Overhead Bins — Can Your Bag Actually Fit

Probably should have opened with this section, honestly. Because for most frequent flyers, the bin situation is what determines whether a regional leg derails your entire travel day.

The CRJ-900 overhead bins are small. Not inconvenient-small. Functionally, genuinely inadequate for a standard carry-on rolling bag. A typical 22-inch roller — an Away Carry-On, a Travelpro Maxlite 5, anything in that category — will not fit wheels-in on a CRJ-900. Passengers attempt it anyway. Flight attendants intervene. Gate-checked bags accumulate on the jet bridge. On a 40-minute connection, that gate-check becomes a cascading problem that ends with you watching your next flight push back through a terminal window.

Struck by this exact problem on a CRJ-900 operating Dulles to Pittsburgh in October 2022, I counted eleven gate-checked bags pulled from the first four rows alone. Eleven bags — on a 76-passenger aircraft. That’s not an outlier operation. That’s standard CRJ procedure at most carriers.

The E175 bins aren’t cavernous by any mainline standard. But they handle standard 22-inch carry-ons in the wheels-first orientation without drama. I’ve fit a Carry-On Max — 22 x 14 x 9 inches — on multiple E175 flights without a single intervention from a flight attendant. The bin opening is wider, the depth actually accommodates rolling luggage, and the design was clearly built around bags rather than briefcases.

Don’t make my mistake. If you know you’re on a CRJ-900, pack a personal item bag and check your roller at the counter. Yes, it’s usually $30-35 on most carriers. It still beats the gate-check scramble and gets you off the aircraft faster. If you’re on the E175, bring your normal bag and move on with your life.

Seat Pitch and Legroom

The specs here are closer than the bin situation — which is exactly why this section needs some nuance rather than a clean verdict. Typical seat pitch on the CRJ-900 economy cabin runs around 30-31 inches depending on the operator. The E175 sits in the same range. Delta Connection E175s operated by SkyWest typically come in at 30 inches of pitch. CRJ-900 operations through Mesa or GoJet land in the same range. On paper, identical.

So why does the E175 feel roomier? Cabin geometry. The wider, more rectangular cross-section means the seat itself offers more usable width — approximately 17.2 inches versus the CRJ-900’s roughly 16.5 inches. A 0.7-inch gap sounds like nothing. Across a two-hour flight, it doesn’t feel like nothing. The E175 tray table also deploys at a more natural angle, which matters the moment you try to open a laptop. On the CRJ, the tray sits slightly more vertical due to seat-back curvature — anything thicker than a slim 13-inch machine starts feeling precarious on descent.

Legroom for tall passengers — I’m 6’2″ and have tested this with full commitment — is genuinely rough on both aircraft. The E175 has a slight edge because the seat cushion base doesn’t intrude quite as aggressively into foot space, but this is marginal at best. If you’re over six feet, exit rows are your only real target on either plane. Check SeatGuru before you pick your seat. E175 exit row on SkyWest operations is typically row 12. CRJ-900 exit row varies by operator but usually falls around rows 15-16.

Noise and Ride Quality

Both aircraft run General Electric CF34-series turbofans — the CRJ-900 uses the CF34-8C5, the E175 runs the CF34-8E5, essentially an evolutionary step in the same engine family. Specifications look nearly identical on the page. In the cabin, they don’t feel identical at all.

The E175 is noticeably quieter in cruise. I’ve made deliberate back-to-back comparisons on similar routes over the past few years — same time of day, similar load factors, similar weather — and the E175 consistently requires less effort to hold a conversation or hear audio at a reasonable volume. Part of this is cabin insulation. Part of it is the slightly different nacelle geometry and engine placement on the E175. Whatever the engineering explanation, you notice it around 20 minutes into cruise and keep noticing it until the wheels touch down.

Turbulence is turbulence — neither aircraft is exempt. Regional jets cruising at 25,000-35,000 feet encounter more weather variation than mainline aircraft running at 37,000-41,000 feet, and the physics of rough air don’t care which manufacturer built the fuselage. The E175 doesn’t smooth out bumpy air. Neither does the CRJ-900.

What the E175 handles better is low-frequency vibration at cruise. The CRJ-900 has a characteristic resonance — a kind of persistent hum — that becomes fatiguing over longer legs. I’ve stepped off 90-minute CRJ flights feeling more drained than after 3-hour mainline segments. The E175 doesn’t produce the same effect, at least not to anything close to the same degree. It’s not a quiet aircraft by any reasonable standard. It’s just measurably less loud in the ways that compound over time.

The Clear Winner

That’s what makes the E175 endearing to us frequent regional flyers — it’s not comfortable, exactly. It’s just less actively hostile. Wider cabin, functional overhead bins, less fatiguing noise profile, comparable pitch but more usable seat width. When you line up the specifics, it’s not a close call.

X might be the best option for checking equipment before you book — and honestly, ExpertFlyer is that tool, as regional booking requires knowing what aircraft you’re actually getting. That is because equipment swaps happen constantly, and a flight booked on an E175 can quietly become a CRJ operation before departure with zero notification from the carrier. ExpertFlyer’s alert system catches that. It runs about $9.99 a month and pays for itself the first time it saves you from an unexpected CRJ boarding.

While you won’t need a full aviation nerd toolkit, you will need a handful of resources. On Google Flights, expand the flight details after selecting a specific departure — aircraft type appears in that view. On airline booking sites, the equipment is almost always listed on the full flight details page. SeatGuru cross-references flight numbers, dates, and aircraft types and returns actual seat maps with dimensions and user-flagged problem rows. Takes two minutes. Saves real misery.

First, you should reroute through a different hub to get E175 equipment — at least if you have any scheduling flexibility and the price gap is under $60. I’ve done it multiple times. No regrets. The fare difference between regional connections rarely justifies the comfort difference when CRJ-900 is the alternative.

Regional jets will never be pleasant. That’s simply not what they’re engineered to be. The goal is finding the version that’s less bad — and the E175 is meaningfully, measurably less bad. Now you know exactly why. More importantly, you know how to make sure you end up on the right one.
