Give it a rest B&B. You didn't pass selection for BA, and as far as I can tell from your numerous postings, the selection panel and its procedures are working well. Failing selection is a bitter pill to swallow. However, many in BA have numerous attempts. When BA re-opens selection, you can have another go.

No-one knows what the continued EU crisis will bring; how long the oil price will remain at its current levels, or the wider global economic slowdown. IAG, being a Spanish registered company, and with a heavy reliance on premium traffic, will no doubt fare quite badly in the coming months and years. Once you get into BA, you will realise that it is a constantly changing business, and those at the helm are quite aware of the long-term need to keep with the times.
