I am boarding a flight on 6th dec via indigo . The problem is , as i am going for next 1 yr allmost i am taking many wearable items with me which is leading to two stolley bags ( 28 inches and 26 inches ) , i am highly suspecting that tht total weight will be above 20 kgs . how much extra i need to shell out ? My first time so being extra cautious.. :S
