Delta and American put travel waivers in effect on flights to Brazil due to post-election civil unrest.
Leftist challenger and former president Luiz Inacio Lula da Silva defeated rightist incumbent Jair Bolsonaro Sunday in a close election that followed a bruising campaign. In the election's aftermath, truckers who supported Bolsonaro have established hundreds of blockades across the country, including some impacting airports.
According to a translation of tweets from Sao Paolo's airport, there has been difficulty accessing terminals in both directions from the Helio Smidt highway.
Bolsonaro, who lost by 1.8 percentage points, has yet to publicly concede, although according to reports Tuesday his administration was prepared to move forward with a transition to da Silva.
Under the Delta waiver, flyers who booked their ticket by today, Nov. 1 for travel to or from Sao Paulo by Nov. 4 can rebook free of charge for flights through Nov. 7 without paying a fare differential.
American's waiver applies to bookings made by Oct. 31 for flights through Nov. 2 to or from Rio de Janeiro or Sao Paolo. Basic economy travelers, who American does not normally allow to make itinerary changes, can rebook by Nov. 3 for flights through Nov. 8.
United issued a travel waiver prior to the election for travel through Nov. 1 but has yet to extend the waiver.
