Throw in Vienna for $496 and Berlin for $510 too. American Airlines launched a major fare attack on United Airlines hubs yesterday: SFO/IAH/CLE/EWR/IAD/DEN with extremely low fares down to $414 round trip for San Francisco to Zurich and $422 round trip to Lisbon, Portugal. There are several other cities in the $400s with Munich $456, Frankfurt $467, Vienna $496 and Berlin at $510 round trip (fares from SFO).
- Denver DEN – Zurich ZRH $443 Nov 7-14
- Cleveland CLE – Munich MUC $456 Oct 7-14
- Houston IAH – Frankfurt FRA $470 Dec 4-11
- Washington IAD – Lisbon LIS $466 Jan 21-28
- Newark EWR – Vienna VIE $496 Apr 2-9
Some of these fares are available from September to April 2017 with only last two weeks of December and some weekends showing higher fares.
Unfortunately, I have not been able to find an applicable discount to these deep discount fares using the British Airways $65 AARP off AARP link. Fares come out in the $600s through that booking window.
