The first portion of the post is concerned with the current 50% bonus promotion, then the remainder of the post tells how to use Avios to best advantage for travel on OneWorld airlines. It is very comprehensive.
Back in April Dan’s Deals posted a chart showing the number of frequent-flyer miles needed from travel from New York City to almost everywhere. Six airlines are included in the chart, as well as Coach and Business classes.
We see lots of deeply discounted airfares from major cities like New York and Los Angeles, but not so often from smaller places like Austin and San Antonio. Now Delta and American Airlines, and their partners, have addressed that with round-trip fares to Europe as low as $529.
Delta and United Airlines are skirmishing over fares from several California airports to Stockholm, Sweden, for August departures. A fare war including American Airlines is continuing for flights from New York to Scandinavia. Iberia Airlines is in the fight also.
Check the airline websites, Google Flights and/or your favorite online travel agency (Expedia, Priceline, Travelocity, etc.) to see what is available. Look for round-trip fares in the $300s from the East Coast and the $600s from the West Coast.
