// REMOVE: Any items that are not in the temporary list should be removed
        List<TravelProfilePopupDisplay> itemsToRemove = new ArrayList<TravelProfilePopupDisplay>();

                    foundMatch=true;
                }
            }
            // If the item only exists in the original list, then remove it
            if (foundMatch==false) {
                // Note: Cannot remove from originalList during iteration
                itemsToRemove.add( originalProfileDisplay );
            }
