That is a good question
XSBaggage. I wonder if these factors are part of it:
- A very great proportion of their pax are US travelling inside the US and do not experience the range of different carriers that we have in Europe.
- Their US pax who do not travel internationally often, probably feel safer to book with a US carrier.
- Their US pax who do travel internationally often, inc C + F, may have employer restrictions to stay with US carriers.
- US carriers may offer financial benefits to those C + F pax.
- US based Frequent Flyer Miles programmes.
