I have never flown BA b/f and I am flying it now as part of my AA MR. I am flying MUC to LHR on Aircraft type : 319BA0947, 07:00. The seat selected for me was 4a, I see there's no 4b but there's 4c. I can't find a seatmap for a 319 that doesn't have row 4 in first or missing seat 4b. I am looking for a seatmap for this plane, so I can pick my favorite seat. In lieu of that, if someone has experience can they tell me if the exit row seats recline fully and have a lot more legroom or if there's any other seat that is much better than 4a. Thanks.
