I think you are worrying about nothing. All airlines have CAA standards to work to or they would never get a licence to fly anywhere. If you want comfort you have to pay for it. If you are on a budget, you take the cheapest you can. Whatever you choose, you know that you are going take off and land. Why the safety issue? are you afraid of terrorists? dodgy food a smelly toillet or a longer that an hour wait?
Just chill and get the ticket you can afford
