Thanks. Yes, I see that the Mennens versus Emirates judgement added clarity in terms of the reimbursement calculation. However, in terms of qualification item 27 would indicate that the Mennens formula applies where the passenger ends up in a cabin class lower than ticketed. So the situation with retickets is as murky today as it was when EC261 was introduced, because an airline can argue that it is obligated to provide carriage in the class of travel to which the passenger is ticketed at the time of check in.
