If we used to make that flight,if the flight number still is IBxxxx,and it is sold through IB's web as IB flight operated by... then i'd say it is our production,taken away
I'm happy to be corrected on this but here goes.
Iberia flights are prefixed IBE. If we take Iberia Express as an example, their flights are operated and marketed with IBS flight numbers. Similarly Vueling operates and markets under VLG flight numbers.
Apart from Oneworld codeshare partners, which airline(s) are operating/marketing as Iberia with IBE flight numbers? What routes?
