International Flights take a little more work as they are currently very high. I booked a couple months ago but still tracking.
Currently Google Flights show
Prices are all over the place
With the prices being so high, I was able to get a United Non-Stop using 100,000 miles per ticket. Since then UA has raised the price to 200,000 per person. Glad I booked when I did.
Even with a free ticket we had to pay $654 in taxes and airport fees. The biggest fee was $255 each for U.K. Air Passenger Duty
