Family in the states Florida invited over for thanksgiving I normally fly BA always have. The current issues at LHR had me looking at KLM via Amsterdam. Anyone give a heads up on whether that’s likely to be better. Flight would be Scotland to Amsterdam or LHR overnight stay then early morning flight direct to Miami.
Flew BA ( partly American) in May to Ft Myers absolutely a nightmare 36 hours late arriving and still waiting on compensation. Return trip was actually fine. Now strikes at LHR etc hence the KLM option.

thanks.

AMS is currently as bad as LHR.

Look at details in the threads on AMS carefully. My impression is that most of the mess involves people trying to depart from AMS. Most connections there don't require a security check, assuming that you stay airside (i.e., no overnight connections, no LCCs/ULCCs that don't permit checking luggage through, etc.) and I don't think your itinerary would require passport control at AMS either. If you're concerned about lost or delayed bags, do carry on only or at least keep necessities for the first couple days in carry on.

You wouldn't *have* to stay overnight at AMS unless you really wanted to; on the days that KL flies to MIA (and it's only 3 times weekly, on Sundays, Tuesdays and Fridays), the flight leaves at 10:25, which means you can leave the same morning on most of the first wave of flights from Scotland (e.g. first flight from EDI leaves at 05:50, first flight from ABZ leaves at 06:00, first flight from GLA leaves at 06:05) leaving you about 2 hours to make the simple connection at AMS. From INV, it does indeed appear you'd need an overnight stay.

You might have a bit of a longer wait at AMS on the return, but my vote would be for AMS over LHR.

You don't have to clear security or passport control at AMS when connecting from non-Schengen to non-Schengen.

The issues with AMS are mostly for passengers originating in AMS - transfers are unaffected. Also...it's highly unlikely that either LHR or AMS will still be seeing the current chaos in November - if only because travel volumes will be much reduced in November compared to the current summer travel peak, and presumably they will both have found and trained more employees by then.

November typically is dead at AMS but with the world cup there may be some additional traffic. Pick the best connection is my advice.

DL is offering same-day connections EDI-JFK-MIA/FLL, and EDI/GLA-CDG-MIA (as AF codeshares), depending on day of travel.
