After reading your story about the Melbourne airport check in time,
I want to point out, Gold Coast Airport has a very big problem which is also preventing "Early" check in.
As repeated to me by a Gold Coast airport employee, the OOL baggage holding room isn't capable of handling all the additional flights that the airport keeps accepting.
As a result, Qantas refuses to accept checked lugguge until two hours prior to departure. and the check in agents are very rude and obnoxious about this. I was a business traveller (Platinum) and I was treated with such rudeness by the check in agent. A second Qantas agent stuck his nose in and remarked "Why are you here so early? - Don't come early... go walk around until it's time to check in - now go away as we have other passengers to check in".
This is something that passengers should be advised about - but we are not. We, the passenger, try to do the right thing and follow the requests by airlines to arrive early... only to be told, you're early, go away!! It's even more frustrating at OOL, as a regional airport, families, backpackers and various other travellers from other remote locations have no choice but to arrive early at Gold Coast airport, as they travel from rural and regional centres to the Gold Coast for their air travel needs. To comply with airline requirements, The ground transportation can arrive several hours early.
As a result of this encounter, we now try to avoid Gold Coast airport where possible and travel to Brisbane for our travel needs. If the airport won't upgrade its facilities, then it has no business accepting more carriers.
What they didn't realise, is that I'm a radio broadcaster and journalist. So I reported this incident on my radio show. In October 218, I lodged a complaint with Qantas, as well as Gold Coast airport - but I did not get a response from iether. As I said during my radio broadcast, Looks like they just stick their heads in the sand, while passengers are the ones who suffer.
