If you buy a cash ticket light and flex(both economy tickets) offer no checked in luggage, comfortflex offers 1 23kg . Paid business is 2 bags of 32kg each. You can always buy more baggage even in the 0 baggage fares. I suggest you book directly via aegean.com if paying in cash

All the above allowances get a +1 bag if you're *A gold
