Hi all!

I'm new to booking award flights and feel like I'm flying in the dark. I'm trying to find business class award availability on Swiss, from LAX-ZHR (nonstop) anytime between February-April next year. I've dug though multiple weeks of results on Expert Flyer, scoured the United award chart, looked on Avianca - all to no avail. I don't know if this is an exceedingly difficult route to find award availability for, or if I'm just not doing something correctly. My husband and I will need to book this flight 2x per year, so I'd like to understand if this will always be an issue or if there are tips and tricks (like looking exactly 300 days out, when Swiss releases award inventory).

Thank you!
