For those following along, we had a rough go of it with AB in July. 6+ hours delays on the way there (we're awaiting our EU 261 cash compensation wire transfer), and a lost bag (our son's car seat) on the way back.

Can anyone advise on how to get lost baggage compensation or even a full report on the situation from AB? I originally filed a claim with Swissport in BOS. However, Swissport and AB informed me that after 5 days (the bag was lost in mid-July), the claim gets transferred to Baggage Express. According to AB, Baggage Express only has email, there is no one I can call, and the last AB agent I spoke with told me to threaten a lawsuit and "that should get them to respond very fast." Turns out, it didn't. Moreover, Chase (whom we have delayed/lost baggage protection with) won't reimburse us because AB won't even give me an official claim, and apparently the Swissport one isn't good enough.

So, does anyone have any tricks, phone numbers, strategies to get AB and/or Baggage Express to engage on this? At this point, it's clearly lost, and we're really just looking to be compensated and be done. Thanks!
