http://www.cnn.com/2011/TRAVEL/05/02/plane.row.numbers/ You wouldn't think row numbering on airplanes would be something worth spending time on, but the new United disagrees. Beginning June 9, the pre-merger United domestic fleet will be getting new row numbers to match the way numbering was done by Continental before the merger. This may seem like a waste of time, but frequent fliers will actually benefit from this change. Today, United's domestic fleet starts with row 1 in first class. Then coach starts at either row 6 or 8 and counts back from there. On an A319, that means that row 24 is the end of the line. Beginning in June, however, that airplane might seem longer. The last row will now be 34. Is it growing? Of course not. First class will continue to start at row 1, but now every domestic airplane will have coach starting at row 7 for consistency. And the exit row will now start at row 20, regardless of what row was before it. That means in the new configuration on an A319, for example, there will be a jump from row 12 to row 20.
