Why is there no 33 on planes?

We used to skip 33 on certain maps to make the [final] row standardized, but the end row is no longer standardized, a United Airlines spokesperson told Travel + Leisure. In short, the reasoning behind having a unanimous seating map is a math equation of sorts.

You might be thinking that the numbers on this diagram are backwards. On a handheld compass, south is 180 degrees (so 18 in runway terms) and west is 270 (27). But the “W” is numbered 9 because the runway number is connected to the direction the plane is traveling.

B and E are omitted so that C and D are always aisle seats. This is also maintained on the bigger A330, where numbering is AC - DEFG - JK. So A and K are window seats; C, G seats with aisle on the right; D, J seats with aisle on the left; B,E,F middle seats.

On many aircraft, the rightmost seats have letter designations HJK, skipping the letter I. This is because each seat has a row number followed by letter; letters that may be confused with numbers (I, O, Q, S, or Z) must be avoided, usually for people with dyslexia.

Commercial aircraft travel at hundreds of miles per hour, and it takes experience and skill to bring a jet engine to a safe stop. A pilot who miscalculates the initial approach can veer off the tarmac or completely miss the runway, rolling over rough terrain or into ditches or bodies of water.

Runway numbers are actually a reference to the closest magnetic heading of the runway. The runway heading is rounded to the nearest 10 degrees, and the zero is removed. This number is then assigned to the runway. Further differentiation can be achieved with letters on parallel runways.

Since most runways are oriented to take advantage of prevailing winds to assist in takeoffs and landings, they can be used either direction. This is why most runways have two numbers. The second number differs by 18 or 180 degrees.

The middle seat in the final seat is your safest bet The middle rear seats of an aircraft had the lowest fatality rate: 28%, compared to 44% for the middle aisle seats, according to a TIME investigation that examined 35 years' worth of aircraft accident data. This also makes logical sense.

These seats are coveted for that extra bit of legroom, so prepare to reserve your seat ahead of time. If your plane happens to have two exit rows, the first row of seats won't recline, so if that's something you want, sit in the second row! Another option is to skip economy altogether and upgrade.

Since there is no middle seats to left of the left aisle and to the right of the right aisle, the letter B is skipped (and K is skipped for the right-hand seats). If this numbering method is used it reduces confusion as A is always windows, C is always aisle etc.

Most airlines have a different fare class for each letter of the alphabet, and this varies by airline: F is first class, C and J are typically business class, and Y is usually economy, regardless of the airline. The assignment of letters to each fare class isn't arbitrary.
