Greetings! First time poster. Using Alaska Miles to fly family in business class on Condor from BOS to FRA. From there planning on a flight on a different airline (most likely BA or Lufthansa) to London. Will be traveling with checked bags. So understanding that we will need to clear immigration/security, collect bags, recheck bags, and then depart internationally again, how much time do we need? Our flight lands at 5:10 a.m. and there are hourly flights basically at 7, 8, 9, etc. I'm thinking the 7 a.m. flight is too aggressive, but the 9 a.m. or later flights too long, so I am leaning towards the 8 a.m. and would appreciate any thoughts or guidance. Also considering shipping checked bags in advance to London to expediate the process.
(As an aside, if the BA fuel surcharges weren't so ridiculous on award flights, this would be WAY easier.)
Thanks!
