My B/F seat was broken on 12+ hour flight TLV-EWR.

At gate in Newark was met by concierge and said "we'd be intouch".

On return flight a few days ago there was a concierge on board greeting passengers. When I told him my problem in previous flight he offered $500 travel voucher or 5,000 miles but wanted to wait and see what the previous concierge did.

On arrival home had letter from Continental offering 5,000 miles. Not good enough.

How do I go about getting the $500 voucher which is much better for sure.

Thanks,
