### RE: Why No B On Planes Seat Plan

Many airlines that fly planes smaller than 3+3 config skip a letter on the 2-seat side, for example if seating is 2+3 the seats will go A C D E F, because B is a middle seat that doesn't exist.

Or the difference could be between First and Coach... if coach is 3+3 and First is 2+2, then first gets numbered A C D F because B and E are the middle seats back in coach. Not all airlines do this but some of them like to keep things consistent at least within the same aircraft, so A and F are always window seats, C and D are always aisle.

This goes out the window if the plane is 767 or larger, though. Delta, for example, assigns letters in order from left to right no matter the config, so in the 2+2+2 of First on a 767, they go A B C D E F, but in the 2+3+2 of coach they go A-G. But on their 777 in BE, they do skip letters to stay consistent with coach. Don't know why the 777 is different, but BE is numbered A C [aisle] D F [aisle] G J and coach is A B C [aisle] D E F [aisle] G H J

An SAA 747 in economy will be ABC DEFG HJK while a 340 is AC DEFG HK

I remember when I could fly domestic jump seats in the good old days, the check in staff created a B seat in business class to give me a boarding pass. This confused more than one F/A when I showed the pass at the aircraft door
After Monday and Tuesday even the calendar says WTF...

### RE: Why No B On Planes Seat Plan

Depends on the system that the carrier uses, but B is pretty common. A lot of systems insist that the same type of seat always has the same letter eg. A is always window, C is always aisle. B is usually a middle seat on the left hand side of the aircraft, facing forward.

Same reason as there is no 'I'. Just as 'I' can be confused with '1', so 'B' can be confused with '8', especially using cheaper printers. There'd probably be no 'O' either!

Not true. A great many carriers have "B" seats.

### RE: Why No B On Planes Seat Plan

One carrier redid the Commuters to ACDF so that they have some commonality with standard gauge narrowbodies....ie a and f are always windows and C and D are always aisles....ending confusion among frequent travelers was the reason given...

guess it makes sense.....but not all carriers follow that....probably has to do with how difficult it is to change seat maps and aircraft signage.

never heard the B looks like an 8 reason before....

I don't think that is the reason. If it were then 2x2 would be AC DE. But when then skip B they also skip E so that 2x2 is AC DF.

 Quoting JGPH1A (Reply 3):A lot of systems insist that the same type of seat always has the same letter eg. A is always window, C is always aisle.

That's exactly what the reason is.

 Quoting Vatveng (Reply 1):Not all airlines do this but some of them like to keep things consistent at least within the same aircraft, so A and F are always window seats, C and D are always aisle.

### RE: Why No B On Planes Seat Plan

BA have a consistent policy through the whole of their long haul fleet. The left hand window seat is always in row "A" and the right hand window seat is row "K". Similarly the central two rows are always rows "E" and "F".

So where there are just four rows as in the 1-2-1 "F" class 744 cabin the rows are "A", "E", "F" and "K" while up the back the 3-4-3 "M" class cabin has all rows, "A" through "K" missing out "I" because of confusion with "1".

The 2-4-2 "J" class 744 cabins have rows "A", "B", "D", "E", "F", "G", "J" and "K" while on the narrower 763s the 2-2-2 "J" class cabin has rows "A", "B", "E", "F", "J" and "K". The 2-3-2 arrangement in the "W" class cabins on the 763 are rows "A", "B", "D", "E", "F", "J" and "K".

So the row adjacent to row "A" is always row "B" and that adjacent to row "K" is always row "J". There is only a row "C" where there are three seats on the window side of the aisle and it is always an aisle seat and is always adjacent to row "B". (The same applies to row "H" on the right side of the aircraft.) So where present rows "C" and "H" are always outside aisle seats.

Rows "D" and "G" where present are always inside aisle seats. Rows "E" and "F" are the two centre rows and are always adjacent but in the 744 "F" class 1-2-1 configuration and the 763's "J" class 2-2-2 configuration they are also both aisle seats. However in the 763 "W" class cabin with its three central seats row "F" is an aisle seat but row "E" is not. In other configurations both rows "E" and "F" are inside seats.

Now I hope that's clear!!!

### RE: Why No B On Planes Seat Plan

The seating arrangement was designed using a 747 as the maximum seating so it went 3-4-3 in other words abc-defg-hjk. A is always a window seat, C always an aisle etc. There are some exceptions but this is the general rule. Of course it isn't a mandated law or anything but rather for convenience.

W on a 763 is 2x3x2 ? How is that different from WT ?

Thanks. My mistake. "W" on a 763 is actually 2-2-2, the same as "J". When I said:

 Quoting VV701 (Reply 9):The 2-3-2 arrangement in the "W" class cabins on the 763 are rows "A", "B", "D", "E", "F", "J" and "K".

I meant to say:

'The 2-3-2 arrangement in the "M" [not "W"] class cabins on the 763 are rows "A", "B", "D", "E", "F", "J" and "K".'

### RE: Why No B On Planes Seat Plan

A= LEFT WINDOW
B= LEFT MIDDLE
C= LEFT AISLE

D=RIGHT AISLE
E= RIGHT MIDDLE
F= RIGHT WINDOW

Fly on a 737 or A320 series aircraft, or any other 3 by 3, and that is the usual designation. If there is no middle seat then they skip that letter. CRJ's and the like, 2 by 2, have no B or E designated seats. An aircraft with a 2 by 3 configuration will have an E but no B. It is the same on widebodies if the configuration is only two seats on the window sides there is no B or E which defines the middle seat next to a window seat.

Incorrect.

Many regional airlines use "B" for their seat assignments. On 3 across configurations, they use A on the lefft, B & C on the right. On four across they use A & B on the left, C & D on the right.

### RE: Why No B On Planes Seat Plan

My appolgies I should have stated that my rational posted is NOT USED FOR ALL airlines but is used by many. Yes some regionals use A/B then C/D. Many would also list as A/C and D/F on a 2 by 2 configuration to be consistent with larger aircraft. Thus an A or F is window, C or D is aisle, and B,E is middle. Examples of this include Air Canad Jazz CRJ's and Dash 8's along with AC ERJ's.

### RE: Why No B On Planes Seat Plan

In the US some airlines (Trans States and Chautaugua coem to mind) have EMBs with no airline livery, so that they can be used for any of their mainline parnters. Problem is their mainline partners have diffrent setups. Had this happen once PHL-LGA. Not only did those New Yorkers have to suffer the indignity of flying a "puddle jumper", they then had to fight for their seat. They didn't seem to enjoy it, but I was entertained.
When in doubt, one B pump off

On a historic note, TWA used only numbers on its widebodies.

Row 15, seat 1 was the wondow seat on the left and 9 (on 767's) on the right. So instead of 15A, you got 151, instead of 15K, you got 157.

You are corrrect for I vs 1 but not for B. The letter B is used on all aircraft with 6-abreast seating, at least every one I've been on. The reason for B not being used on aircraft with less than 6-across has already been explained, i.e.for consistency between window and aisle seat designators on different types. This is a very common practice.

Many carriers (but not all) do the same thing on widebodies. Most 10-abreast widebodies like the 747 usually have seats designated ABC DEFG HJK. Carriers that also operate other types with less than 10-abreast usually delete letters but keep the window/aisle seat identification consistent. e.g. An 8-abreast A330/340 will probably have seats designated AC DEFG HK.

There are other variations depending on the carrier but I think that's the most usual practice.

I remember this as well. However when I flew on TWA in March 2001 the 767-200ER's I flew on from CDG to JFK TW925 and JFK back to CDG TW924, I sat in seat 36C an aisle seat in the last row on the left hand side.

Well I guess I know why... lol... at the time they were already part of AA and probably adapted to their seat numbering system.

Does anyone know when exactly TWA changed this? I still have the boarding passes and I'm 100% positive that the placard beneath the overhead compartment on the plane said: 36 A (window) C (aisle)

So they changed that even though the 767-200ER's were quickly withdrawn from service after TWA was bought out by AA. What a waste of money!

TW always put a dash on widebody seat numbers, the seats above were 15-1 and 15-7.
