Thanks for the advice, may i clarify i am not blaming anyone i know it is my mistake just shocked at how inflexible the system is. I know it is a stupid error and not more can be said about that. I would have expected a fee to make the amendments. I will pay for the new tickets not the parents. I don't think they will risk the airport as it is critical they get on the plane. Following many calls and some inside info form BA i understand the agent holds the keys. Just need advice on what can be done or is it just suck it up. I don't think the T&C's are very clear and no mention of codeshare etc.
