I've got a superlight fare this week.
Planning on bringing a bigger backpack, towards 55cm.
Hopefully no issues with that.
Could pay £16 for the bag now or just hope my OWE status is fine (or no sizing).
Sitting in a bulkhead, so can't put a bag under my seat anyway.
Can't say I've seen anyone checking bags at the gate at LHR.
BA flights and AY business coming back, so no issues expected there.
Got a PE fare later in the year and that comes with a personal item and the 55cm bag.
