Booked IAD<->WAW today for a May trip. Looking at the livery and equipment options, I chose LH because of the new 787-8i going between IAD and FRA. Because it's business travel, I have to book refundable fares. I was very surprised to be selecting First Basic II over Business Select II. First was $100 cheaper in fare + taxes than Business. The refund fee is a little more, but that's not what I'm expensing - I'm expensing the total fare + taxes. The website said First Basic II would not allow me to reserve seats; that they would be assigned on check-in. When I paid for the fare, however, it allowed me to select seats. Just thought I would share in case someone here finds themselves booking refundable business on LH. Look at the First Basic II fare!
