Air France has round-trip flights from Dallas (DFW) to Budapest or Bucharest (BUD, OTP) for $599-$640 with a connection. Flights October to February. Departures on Monday, Tuesday, Wednesday, and Sunday. 7-day minimum stay required.
Air France has a coupon-code for $50 off, but it doesn’t work because the code requires a base-fare of over $250 each-way. Most international fares on Air France such as this one have very low base-fare costs, (between $30 to $60) and very high airport taxes/fees (about $400). Which means that in almost all cases, the Air France coupon-code is an invalid waste of time.
