Why is 7B not there on A319 seat map
 

Sorry, but I could not get answer after a reasonable search. I have a couple of flights this week in Eurotraveler on A319 with my wife (both G). Row 7 is first row but seat 7B is not showing. Any reason? Are 9A and C better on A319? Many thanks

The first row of Euro Traveller is always in Club Europe seating configuration on the left hand side, except on non-convertible configured A320s.

Thanks. I guess that it means a risk of being kicked out in case more Business pax?

You have that risk in any of the forward ET rows, as the curtain can just move back.

But after OLCI, it's generally quite a low risk.

I would choose 7AC over row 9, those wider seats at the front of ET are great! Row 9 is good on the A319 also, but on a busy flight having a middle seat free is great! 7AC are widened with a smaller, unsold B seat, also good for storing stuff during the flight like an iPad, newspaper, laptop bag etc.

The risk with choosing 9AC is that there could easily be someone in the middle seat, on busy flights some people often ask for an exit and happily take it if it is only a middle.
