Me too. I like both the airline and DXB airport, and I like that they refunded my ticket within hours when flights were suspended between Dubai and Dammam because of COVID. That was in July last year. Gulfair also refunded, but took their time. Malaysia were also quick.
Looking at the post you pasted, different sections of ‘economy’ are priced differently on different days. Emirates do not guarantee you can just switch your ticket without paying more. They guarantee there will be no charge just for changing. Re this thread - the author does not explain why they are unhappy with Oman Air, so who knows.
Did I say there were no buses from the Southern Terminal? No. And I specifically mentioned that there were buses from the airport. You know, that part where I say ‘there are buses from the airport’? Doubtless the person asking the question will be delighted you have a car. Bye now. 😊
