Airport parking is very expensive eg 25% of the cost of the fares for 2 on a flight into Europe. For that one expects 5 star service, and it isn't provided. The signs telling you which parking areas are being used could be clearer. The entrances and exits could be marked more clearly. The bus transfer could be more frequent and tailored to flight arrivals and departures. On our last return on 24th June at about 10pm, we were told by the bus driver that we had to read the bus stop numbers for ourselves in daylight hours. It wasn't daylight, it was after sunset and overcast, it was raining so that windows were covered in water, and there was some idiotic advertising wrap over the bus which made it impossible to see through the windows anyway. The driver did in fact call out the bus stop numbers, but that initial comment was unhelpful and annoying to people tired from a long day's travelling. For the large amount of money charged, you need to do better. If you didn't have a monopoly, your customers would desert you.
