Question for the Board: What is a W9M?
I'm looking at a trip to PBI next month and the equipment listed for JFK-PBI is a "W9M". The plane has 4 rows of F 1-2; 5 rows of C+ 2-2; and 11 rows of Y 2-2.
I get 76 total seats, which is the same as a CRJ-900.
Is this a new version of the CRJ-900? By comparison, how big is the 1000 series airplane that DL is acquiring from Bombardier?

I can't remember where I read it, but I remember DL saying they were replacing two rows of Y with C+ on the CRJ900s. So yes, this is a new version of the CRJ900. I believe these mods started at the end of last year.

Who is the operating carrier?
------------------- Added -----
Most likely a 175 with the 2 rows of Main Cabin Preferred changed to C+

A W9M is the CASS aircraft type for Endeavor Air CRJ-900s. Each of Delta's subfleets can be referred to by three different abbreviations: the Indicator type (most basic), the aircraft type (common), and the CASS type (mostly for internal use). Endeavor Air CRJ-900s are CR9, CM9, and W9M respectively. I believe the common use of the letter W in the CASS types indicates Comfort+ seats because they were added when Comfort+ was being rolled out, but that specific factoid is just a rumor I've heard. (Edit: Now that I re-remembered that CASS=computer-assisted seat selection, I think this 'rumor' is true because the new seat maps with Comfort+ as its own fare are different than the old seat maps. Comfort+ is now displayed in its own cabin instead of combined with Main Cabin, so the W letter in the CASS aircraft types means that the aircraft's seat map has a segregated Comfort+ cabin.)
Some others:
Aircraft types with only one subfleet (like the 717) have the same Ind and AC types. Aircraft with more than one subfleet (like the 757) have more than one AC types (like 75D, 75S, 75G).
Edit: I don't think the CASS types are meant to be used on delta.com. I think the Ind types are intended for use because they're more recognizable and have been used most the time.
Some others:
- CR9, RJ9, WR9 (SkyWest CRJ-900)
- 319, 31J, W1J (132-seat A319)
- 320, 3KR, W2D (160-seat A320)
- 717, 717, W17
- 73H, 73H, W3H
- 739, 739, W39
- 757, 75D, W5D (199-seat 757-200)
Aircraft types with only one subfleet (like the 717) have the same Ind and AC types. Aircraft with more than one subfleet (like the 757) have more than one AC types (like 75D, 75S, 75G).

Btw -- has anyone noticed the DL has gotten less-specific, as well? Sometimes on the app or on DL.com the aircraft type will just say something like "Boeing 737" or "Airbus A330" or "Boeing 767" without referring to the variant.

Cass is Shena's cousin. Computer-Assisted Seat Selection is the computer system that automatically assigns seats to passengers when automatic seat assignments are needed, so you can blame Cass when you get rebooked into a middle seat.

The Endeavor 900's all have the 2 additional rows of C+. All F and C+ have in-seat power.
What's also very good news is that the stupid limitations regarding when is-seat power was active have now been removed and in-seat power is available whenever the A/C is powered, either externally or by engines/APU and the Captain has switched it on.
The original conditions which had to be met for the seat power to be on were:
1. The seat belt sign had to be off.
2. 2 of the 3 generators (the APU counts a 1 in this case) had to be running.
3. The landing gear had to be up
4. The flaps had to be at 0 deg (fully retracted).

My Delta connection carrier flights almost always show the CASS type on the seatmap rather than the common type. Seems to happen sometimes for partner flights as well.
