There are limited round trip airfares travelling from many US cities to cities in Switzerland and Germany starting in the $400s on One World Alliance airlines such as American, Iberia, Finnair and British Airways.
I check a couple of random ones and attached a screenshot of Tucson AZ to Frankfurt for $477
So….here’s how to book it.
- Use Google Flight search
- Plug in your to/from cities
- Look at the calendar for your prices…cheapest one is bolded green
- Click on it and see available return dates
- Use those dates on Expedia (usually $1 cheaper) Priceline , Orbitz or the actual airline directly.
