Hi everyone, I have a few questions about seat selection. I have two flights (same trip) in a week, and I haven’t selected any seats yet. The flights are: Frankfurt-Mumbai and Mumbai-Chennai. All aisle seats are currently available only for a fee. My questions is, will standard aisle seats be available during online check-in? Or should I just pay and select aisle seats now? Thanks for your help😄
