I booked a series of flights on United's website for a trip to Europe involving both United and Star Alliance partner airlines Adria and Austrian Airlines. On the leg from Skopje to Vienna, the Austrian Airlines flight was delayed from early afternoon until the next morning. This resulted in me missing an overnight stay in Frankfort, with a hotel reservation which was too late to cancel, while also requiring my return to a Skopje hotel overnight. The airline offered me compensation for the delay plus hotel expense, but wants my bank account number transmitted by email or given to a caller, which I am reluctant to send over open lines. They will not send a check or issue a flight credit, nor allow me to send the info via fax or other more secure means. Is this the usual practice of reimbursing for delayed flights? I am suspicious of sharing my bank account details with unknown callers or risking it being hacked in an email message. Banks and hotels usually do not allow documents to be sent via insecure methods that the airline insists I use. The Austrian Airlines callers say that they will close the case without making a payment if I don't simply give them my banking details over the phone or send it in an email. After I complained using the contacts shown on Elliott.org, they reopened the case but offered only one other way to be paid: sending my banking info to them on their contact form. What do you suggest is an appropriate way for me to handle this? Should I protect my bank account and let the money go, or is it customary to be paid this way? It seems very strange to me that the airline can't provide a comfortably secure way to pay its obligation under EU law.
