Sorry HABs but my point is that its not 90 days or 180 days after the flight date, the retention period starts from the payment date, regardless of the flight date..
..and as for payment for non- refundable items, it is possible that E clear have a right of offset against monies that they will have already forwarded to Globespan for flights which now won't be performed and will have to refund.
There's two sides to this, its not as simple as is being suggested.
