maybe they refer also that they lift the restricted operating hours and can stay open as normal operating hours, could be good if that is the case? 🤷♂
You can always upgrade at the full price. In normal times sometimes you could have one for free if lucky. If they overbooked their flight (what most companies as hotels do, calculating last cancels into the system) Free upgrade as first class or business is not full, cost them less than have a call on the gate to pay new ticket, hotel and give extra pocketmoney for dubbel booked seats... So don't believe when you got a free upgrade it si because you look so important... 😃 But I wouldn't count on that in these times on long distance flights .... But half a flight upgrade you should ask on the desc if they have one manned and is possible... You have 2 boarding passes anyway if you make a stopover...
