Iberia is to ramp up its flights to the US this summer, with the resumption of three routes to Chicago, Boston and LA.

The carrier resumed services to Chicago yesterday (June 1), with three flights per week (Tuesdays, Thursdays and Saturdays) during June, and an additional Sunday frequency in July and August.

A thrice weekly service to Los Angeles will follow from June 30, and there will also be three flights per week to Boston from July 1.

The three routes will join existing daily services to New York and Miami.

To encourage bookings Iberia says it is offering return fares to Miami from as little as €215, New York from €239, Chicago from €259, Boston from €267, and LA from €449.

Heathrow airport (home to Iberia’s sister carrier British Airways) this week renewed calls to restore transatlantic routes, warning that if the US is not added to the green list “there’s a risk that these US visitors could go elsewhere”.

Iberia also recently increased the number of seats which can be booked using Avios on flights across its network from July 1.

The carrier said that on average the minimum number of reward seats which can be booked in its Tourist cabin had been doubled.
