wait at the airport if you prefer to do a business class upgrade – be nice to airline staff – usually the upgrades online or before the flight day costs more
don’t waste money on bottled water at the airport – carry an empty bottle with you and fill it up at the water cooler
the same applies for food at the airport
freeze your liquids to avoid checking a bag
you can find better deals than the duty free shop
the best days to buy tickets are tuesday and wednesday – prices tend to drop before and after a weekend
onboard purchases are overpriced – food on the flight , that is
take a cab / public transport to the airport – parking is expensive at the airport – the longer your trip , the more expensive it gets
don’t exchange money at the airport – do it outside , if really necessary , get enough money for the cab ride and then go to a local bank
it pays to stay loyal to one airline
