The 763ER on the ATL-HNL is only temporary, probably due to too many 764s going in for scheduled maintenance, and will be gone soon. If you still want BE to Hawaii, the only alternative will be to fly to OGG, which will remain a 763ER, as the 764 is unable to make it to ATL from OGGs runway. So either fly BE to OGG and jump aboard HA or AQ for a short hop, or go for Domestic 'First'.
