Hi there, first time poster, long time reader.

I have flights booked to, around, and from Australia in April on Qantas. I will be flying in WHY and would like to ask if anyone could tell me the following.

What do the letters mean after Economy? Economy (Q), Economy (S), Economy (M) etc? What will it affect?

Me and my partner are on the same flight, but I have (S) and she has (M). We didn't book together, but at the same time on their site.

Anything else I need to know, or that can help me? First time I've flown Qantas. Have signed up for FF club, every little helps lol.

Thanks. ^
