Heart have letters of intent for more than 100 aircraft. It's unclear how far they have actually come in the design process. The official plan is for first service in 2028, so this question gives them a fair timeline with one extra year.

For this to resolve "Yes" it would need to:
- Be clearly operating for an airline (preferably painted in it's livery)
- Have passengers that, at least for the most part (a couple of journalists or VIPs are ok) are paying for their tickets.
- The tickets need to be bookable through the airline's normal website.
- The aircraft may be propelled by batteries or by a hybrid system.
- The flight needs to be at least 100 km from point A to point B (great circle distance as obtained from gcmap.com)
