1. An additional 5KG is priced at $25 per KG and $125 in total. This is the same price advertised on EK website for buying baggage at the airport. Buying online should give a 50% discount, i. e., $12.5 per KG and $67.5. What am I missing?
2. On the return, I have one flight with FZ and therefore I cannot buy extra baggage for the return on the website. Any way I can overcome and still get a discount?

In addition, some carriers give 10% grace for baggage. (So 30KG limit becomes 33KG limit). Does EK have some kind of grace too?
