You’ve bought your cheap ticket and you’ve arrived at the airport. This is the wrong time to find out what you can and can’t take on board. You will have to bin all those cheap drinks you brought with you for the journey (or even in the shops before security) and your excess baggage charges may triple the price of your flight.
Regular travellers will be used to seeing the bins full of drinks bottles near the security gate and watching people frantically switching clothes between cases trying to get within their limits. Luggage allowance is rarely taken into consideration when buying a flight. You should pay it some careful thought though as the slight increase in cost between airlines may be worthwhile for the extra frocks that you can take with you.
Also do you really want to throw that expensive perfume away? This section goes through the basics of luggage allowances, and also suggests some websites that can help you to pack.
