I chose TigerAir as it was the cheapest flight to Melbourne at convenient time for me. Cabin was clean, flight was punctual. Being a short flight, lack of entertainment wasn't an issue. Sydney Domestic airport is easy to travel from city but the station access charges are too expensive for the distance travelled on public transport. Melbourne LCC Terminal was basic which served well for customers of TigerAir. Easy to navigate being a domestic terminal.
Melbourne doesn't have much choice in terms of transport. Either its a taxi /pickup service or skybus if someone does not have personal transport. Travel on Sydney - Melbourne route and return - to city and from airport is 1/2 the cost of one way flight.
