I missed my flight. Had an * hour drive before and there was an accident and therefore a traffic jam. Took a detour and got stopped by police for speeding. Paid the fine, but they stopped me for some time and then I missed my flight. I also had to give back the rental car. It's technically a now show for AF. There is a connecting flight. The agents on the ground told me I would need to cancel and get back my taxes. Local customer service is always busy. I'm from the US with dual citizenship. but since it's a flight from Europe I would prefer a local phone number. There are no issues with visa since I have an EU-citizenship. I would like to change the outbound flights. The inbound flights shall remain as booked. According to the terms of AF it would be possible for a fee. Neighter I nor the ground staff could access new flight segments, because it's apparently a now show.
