Arriving 35 min before a flight?
I know Cooly and 35 minutes before a flight is more than cutting it a little fine.The problem these days is that they still think they are catching a bus but you get what you pay for.
The problem with in cabin bags is that everyone is trying to save money and take carry on bags.The reason staff don't stop everyone is that they are probably sick of these fights.That and they are not paid very much to care in the first place.
It all comes back to my point of you get what you pay for and that goes for the pax and staff.
