Reply To: ESTA required for a connecting US flight?

[Norwich]

Thank you everybody for your replies. ESTA it is then!
The flight from Heathrow to Miami is BA207, then it’s BA4984 (operated by AA) to Lima. 2hr 35mins at the airport, I’d assumed the airline would take care of the baggage, i’ll ask the question at Heathrow check in. The holiday is on the TUI website under Treasures of Peru – basically a glorified coach trip, but it does get me to visit Manchu Picchu, a place that’s always fascinated me. Thanks again everyone
