Thank You all for quick reply! I deffinetely will look into booking classes, seems like that's what I was missing out! So after Your advices, i want and try to book some flights from LH and SINGAPORE AIR but coudn't find the booking class option... so another rookie question here- how do i know what class will be my ticket issued in? Let's say I'm booking LH from Fra to Sin on business, how do I know which letter (class) will I be in?! Thanks for all the help!!
