If you read the small print, follow all the rules and treat it as a bus service then you shouldn’t have a problem. Unfortunately legacy airlines are following their lead, previously there was a clear distinction between full service and low cost, the full service gave you meals and a baggage allowance whereas the low cost charged extra. Now these are add ons to an already higher fare. If it wasn’t for the down market airports that LCCs use, there would be little incentive to pay for a full service airline.
