That would be a nice glitch before the end of April to book flights like EDI-LON-NCE, fly the EDI-LON then cancel the 2nd leg and expect a refund of everything getting a free EDI-LON

OP - is this a one-way ticket or part of a return flight? If the outbound flight to NCE is not taken you may find other sectors on the same booking, if there are any, are cancelled automatically
