One of the features of airline’s code sharing is it is meant tooffer you a much wider range of flights with only having one ticket rather thana range of tickets for each leg of the journey, so for example, you can book a round the world ticket, using 3 or 4 airlines, but only have one ticket.
This is fantastic for the traveller as it means less paperwork, more routes, more airport lounges and also the respoinsibility for getting to the airport on time for onward connections is with the airline as opposed to the individual.
It’s also fantastic for the operator as they can advertise and sell more desitinations without increasing costs associated with increased aeroplanes, staff, land fees etc.
But there is a drawback as I found when I bought a round the world ticket with One World.
The ticket I bought saw me fly from London to Singapore, then on to Perth in Western Australia, then on to Melbourne and Sydent, then the West Coast of the United States, with Toronto and New York being my final destinations.
The only problem I found out was that the hand luggage allowance on British Airways was considerably higher than on its other One World Alliance members, especially Quantas. In fact Qantas made me weigh my bag for the four flights with them and although it was only 12kg nearly half the hand luggage weight allowance of British Airways, it exceed the weight allowance of Qantas by nearly 5kg so I had to check it in. Luckily for me I was flying only with hand luggage and therefore didn’t face any extra baggage charges.
It is ridiculous in my opinion that when you book a ticket through an allowance that they don’t have one policy for hand luggage, even when those airlines are IATA members but do not subscribe to the IATA’s guidelines on hand luggage allowances.
