Not for booking flights
For Whatever you do use this app, it wont be for booking flights. The calendar where you choose dates is off (day of the week doesnt match the date of the month for that year), then you realize that its labeled a month behind incorrectly (July is actually August etc). Then when it shows you the flight options and you click drop down to see detail (like lay over times etc) it only shows you the fare level option and after you chose, it jumps to the return date flight options.
The only good thing about the app is that it lets you add the Iberia card info to your passbook on iPhone.
