ECBI was useful when it was first introduced, today not so much.
When I have a B group boarding pass, I like that infants and young children board before I do. That way I can easily avoid those that are OOC (out of control)!
Gracie - FYI - Any passenger is allowed to sit in any unoccupied seat, there is NO saving of seats. Family boarding is for ONE adult for each child under four years old.
I have heard that family boarding is sometimes cancelled by the gate agent due to the large number of families flying out of MCO.
All good, in theory!! SW seldom takes any stance when it comes to saving seats. I sat and watched as about 9 people boarded right after me. They proceeded to takeup 4-5 rows of seats. Two in each, one in the remaining row. They left the dreaded middle seat open. Well...as more and more people boarded, the FA came over the PA and announced that it was a full flight and there weren't going to be any empty seats!!! That group stayed where they were. About 3 mins later, the same announcement. Well....you should have seen those people move around!!! They were frantic! Seems that they wanted to have those middle seats stay empty so they had more room and no nasty old strangers sitting with them!!! They scrambled to rearrange themselves so that they had as few strangers sitting with them as possible!! There were some lucky people in the C group that figured they were going to be split up all over the plane..and found themselves with seats together, in the front of the plane!!!
But, generally speaking, a FA won't make an issue if there are a few saved seats. If you try to plop down in seat 12A, because there is no one there, but the person in 12C says that their husband will be sitting there? Sure, policy 'says' you can sit there, but in all reality, the FA isn't going to side with you unless there are no other seats on the plane!!!
And Family Boarding?? Yeah, we all know what SW says...whole different thing in reality. They won't allow (at least to the best of my knowledge) the immediate family of mom, dad, little Joey aged 3, little Sally aged 7, Bobby aged 10, and then Gram, Grampie, Uncle Fred, Auntie Joan and the cousins all board together. But they will allow the immediate family of 5 board together. And that irritates me. They could allow just mom and little Joey board and then the remaining three get to stay in their assigned spots.
If you get enough families doing this, it really puts those in the B group behind the 8-Ball. And forget the poor C group.
