There is a huge difference between the terms "the customer is always right" and "the customer comes first". The former simply means that no matter what happens, even if imminent danger is present, the customer ought to be followed. The latter on the other hand means that the customer's safety, comfort, and expectations are all met equally. A customer who travels by air has one primary goal in mind, and that is to get from point A to point B safely.
During every flight, we always hear the cabin crew say "In preparation for take-off, please make sure that your seatbelts are fastened, window shades up, tray tables stowed, and seats in upright position" then followed by a "we will be dimming the cabin lights for take-off...". Same procedure also goes for landing. We may now be wondering why we have to follow all these, and the answer is simply because of safety.
It has always been the attitude of many passengers to stand-up right after the aircraft lands and taxis to the parking gate. They do not see the danger of standing-up while the fasten seatbelt sign is switched it which could lead to injuries or even death. Airline policies do state that the fasten seatbelt light has to be followed where we have to remain in our seats until it is switched off.
If you are used to flying full service airlines or perhaps, seeing the ads of legacy carriers, we might get the impression that all airlines provide similar inflight services such as free food, free overnight kits, free blankets and pillows, free snacks and more, Suddenly when you stepped into the aircraft of your airline, what? No blankets?No pillows? No free food nor snacks? No business class? Small legroom? Well, your airline then must be a low cost carrier!
We all hate delayed flights. As passengers, we do have a schedule also to follow when we get to our destination and a delayed flight would ruin everything. Of course, this is something we do not like. Guess what, airlines hate delays too. Pilots hate delays. Flight attendants hate delays. Ground crew hate delays. In most cases, this is something beyond their control and they are also under strict instructions to follow certain protocol for the safety and security of all passengers.
