NM, I understand the rule of flying coupons in order. But in reality the LHR-VCE-LHR segments would most likely be booked on a separate PNR. And if I then turned up to check in for the next segment, how would the check in agent know if I had flown the segments other than the fact that the coupons were missing? It would be different if all segments were on the same PNR (ie dated coupons).
Have to say i have had experience of getting away with flying coupons out of order (inadvertently) with success (or check in agent error) but wouldn't rely on it.
