BERLIN (AP) Germany's Lufthansa airline says it is canceling some 3,800 flights because of a three-day strike by the pilots' union later this week, affecting 425,000 passengers. <br />
<br />
Germany's biggest airline said Monday the cancellations include domestic and intercontinental connections and are being done in preparation for what is expected to be ``one of the biggest strikes in Lufthansa's history.'' <br />
<br />
Lufthansa says even though the strike starts Wednesday, some Tuesday flights have been canceled for logistical reasons. <br />
<br />
Lufthansa, Lufthansa Cargo and the company's budget airline Germanwings are all affected. <br />
<br />
Lufthansa already had to cancel hundreds of flights last week when public-sector workers went on strike at seven German airports in a dispute that had nothing to do with the airline.
